Marlene MacCallum often applies unusual folds in her works. They appear in sleep walk (2024) and The Shadow Quartet (2018-25). With the two works below, however, — as with Chicago Octet (2014) — the fold becomes central to the whole work. Any other structural presentation would not deliver the precise fusion of image, text, and material to deliver the metaphor embodied by the work.

Artists’ statement: Rise is a collaborative artwork by Marlene MacCallum and Deborah Root. This piece grew out of discussions about our shared fascination with the implications and meanings of the fold. The images and poem evolved through a call and response process, sharing them back and forth. The miura fold structure was selected early on for its structural strength and the way it allowed us to take a seemingly small object that expanded quite surprisingly to reveal a large field of imagery and poetry.
The fold is named for its inventor, Japanese astrophysicist Kōryō Miura.
Lightweight(2015) Ana Paula Cordeiro Custom storage box with passepartout on cover with title printed on translucent paper with colored diagram beneath and sculptural element inside top. Three-part construction Limp Vellum binding on dyed parchment. Box: H215 x W224 x D47v & D53r. Book: H190 x W215 x D18 mm [90] pages. 88 + 2 half pages for colophon. Edition of 21 sets, copy bound on request. Acquired from the artist, 27 August 2025. Photos: Books On Books Collection.
Dating back to the 13th century, the limp vellum binding for books involves a parchment or other flexible covering material that is the sole component of the cover. No stiff boards. It attaches to the textblock usually by sewing and without adhesive. According to the American Institute for Conservation, it was not merely a temporary solution until a more luxurious one with boards and ornamentation could be commissioned. Its presence in collections, its variety of formats, and its superior protection of works proven in the aftermath of the 1966 flooding of Florence, all suggest that, for a time, it was deliberately chosen for joining the artistic with the functional.
Ana Paula Cordeiro’s Lightweight is an artist’s book that pays elaborate homage to this distinctive form of binding. It weaves together metaphor, structure, material, and content in extraordinary ways.
Begin with the container, which offers a multitude of metaphors. On top of the cloth-covered box, a rectangular window has been cut. To look down through this window is to begin peering into the past. Beneath the translucent sheet bearing the title, a print motif appears whose mingling layers suggest the water, paper, ink, and silt that had to be sifted to save a Renaissance legacy of manuscripts, incunabula, and books from the Florence flood of 1966.
Left: passe-partout (window) on box top. Right: recurrent print motif appearing later in the book.
That strata of links running from blue to rust to gold becomes a recurrent print motif in the book, suggesting abstractly another metaphor: that of a continuum with endpoints playing off one another. As soon as you pick up the Canapetta cloth-covered box, the title itself — Lightweight — sets in motion a fresh instance of this continuum metaphor. Floating above the recurrent print motif, the title contrasts with the weight in your hands. As if to underscore this diametric contrast, the corners of the top and bottom of the box sit flush at the ends of one diagonal but gap at the other, easing the lifting of the weighted top from the box.
Inside, other decorative features offer further dual functionality. The sculptural element that provides the top’s weight also serves as a protective mould inside for the book and mirrors its dominant and recurrent physical feature: the creased shape slanting in parallel to the title slip tacked to the cover. Cordeiro refers to the creased shape as an “angled beam”.
For her, the angled beam distills the essence of the limp vellum structure and “supports” the variety of contemplation she pours into it. The angled beam puts forward the limp vellum structure as a historical link from binding’s past to its present. It stands for the binding structure’s durability, again linking past to present. Its linearity stands in for that continuum. It prompts thoughts of other continua along which one thing becomes another such as the line between night and day (twilight), between light and shadow, between one season and another. It evokes the continua between extremities, between the ordinary and the extraordinary, between mental acuity and dementia, and between life and death.
Following Emily Dickinson’s injunction — “Tell all the truth but tell it slant” — Cordeiro plants other angles in Lightweight. The ribbon tape that lies under the book is stiff, not soft and flexible, and it twists once and folds twice into an angular tool for lifting up the book. The trim of the book’s top and bottom edges slants. Creased into the covers, end sheets, and text block of this limp form, the angled beam is a physical constant echoing the metaphor of a continuum whose endpoints contrast and balance with one another.
Altogether there are seven gatherings in Lightweight. The “prelims” gathering provides the historical context underlying Cordeiro’s homage. Note the artist’s wish expressed in the envoi to this artist’s book in our hands: “May its message be its medium, may its artistry embrace eternity”. Here, Cordeiro introduces that self-reflexivity we expect in the best of artists’ books.
After the prelims gathering, the other six gatherings are labeled. In addition to bearing the creased angled beam, all six carry an “on-end outline” of it (see below). The five that are numbered, lettered, and labeled introduce themes reflecting different responses that relate to the continuum motif.
The Part 1, Section R gathering has announced cryptically that color will merge with form. How will this happen? As you turn the page, the opening text suggests how — along a continuum: “Continuum (measurement), anything that goes through a gradual transition from one condition, to a different condition, without any abrupt changes”.
The spread lays out this definition in a peculiar manner that seems to contradict the definition. On the verso page, the definition seems to run abruptly up against the seam, which bumps the words “abrupt changes” to the next line, while the recto page presents a truncation of those words: “rupt changes”. Hold that puzzle for a moment. So how can color and form be on a continuum? And will they merge gradually or abruptly? On the next spread, Cordeiro answers with the Sanskrit word rupa, which represents “color” and “form” and from which the section draws its label “R”.
un extremo se conoce bien por otro [one extreme knows well its other]
So, the merger is etymological. But at the same time, another spectrum comes into play: the color spectrum and the blue and red at its opposite ends. On the spectrum, of course, one gradually becomes the other, enacting the expression “un extremo se conoce bien por otro” [one extreme knows well its other]. If this seems a stretch, the next double-page spread reassures us that “continuum” has additional linguistic as well as mathematical roots.
Before the reassurance, however, we come back to the puzzle of “rupt changes”. Again, on the verso page above, the definition of “continuum” runs pell mell into the crease. To solve the puzzle, we have to look more closely at the structure of the Section R gathering. It consists of three oblong folios folded in half. On the reverse side of the center folio (what would be pages 5 and 8 of this gathering if the pages were numbered), the definition of “continuum” has been printed so that the fold splits the word “abrupt” between its syllables: “Continuum (measurement), anything that goes through a gradual transition from one condition, to a different condition, without any a | brupt changes.” In effect, the layout draws attention to our perception of breaks in continua.
View of “pages 5 and 8” separated by a detailed view of the break in the word “abrupt”.
If Section R has not prompted the reader to propose questions about the structure of the book or this book in particular, the Part 2, Section Q gathering provides a series of oblique questions very much focused on that but also on metaphorical matters. Again, what happens structurally in the gathering and on the surface of its pages presents puzzles and hints at solutions.
The geometrical images associated with the first question (“Do they hold surface tension like a soap bubble?”) seem to float or progress across the double-page spread, breaking up to punctuate the question. Reminding us of opposites and abrupt changes, the angular yellow overlapping squares and triangles puncture the text’s round verbal soap bubble. Before we can ask to what or whom does “they” refer, we are prompted by “Question:” to turn the page.
The next question (“Do they prowl like felines?”) prods at the unasked question: what or who are “they”? How is it that “they” are like prowling felines? Again, the images seem to progress across the spread, with the first image’s central diamond shape disappearing to leave the curvilinear second shape leaning over the printed question. Might these be diagrams of the limp vellum structure’s sewing holes and lacing? If so, has Cordeiro found another metaphor for limp vellum structures in the supple and sinuous strength of prowling felines? Do “they” refer to limp vellum structures?
The next question turns directly to a functional attribute of the book structure: turning pages. The yellow print gives an ambiguous view. The two-dimensional representation of the angled beam fluctuates between a mountain view and a valley view. Are we looking down on the splayed spine of a book or its gutter with pages splayed open? Either way, the print angles away from the physical angled beam, which sets up a metronomic pattern in the spread — the beam leaning to the right, then to the left, and again to the right — or a page turned to the right, then to the left, and back again to the right — or mountain fold, then valley fold, then mountain, then valley (the gutter), then mountain, then valley, then mountain until we come to the ambiguous two-dimensional print. Again, this is a continuum, and “they” seems to refer to limp vellum structures.
The next question enacts itself. To read the mirror-written script, we have to turn the page and look through its surface to the right-reading words: “Do they depend upon the turning of”. The question completes itself in a curious (again) metronomic motion. The syntax draws our eyes to “PAGES” on the right, while the oversized punctuation mark syntactically draws our eyes back to the left. The play between the reversed writing on a recto page, the right-reading script on the verso, the display type on the next recto, and oversized question mark on the adjacent verso provide self-reflexively an affirmative answer: Yes, limp vellum structures depend on the turning of pages.
Part 3 introduces rather more esoteric continua with which Cordeiro seeks to connect the genius of the limp vellum structure. The Section letters M, M and G are her reminders-to-self that this section excerpts passages from William James’ The Varieties of Religious Experience (1902): one on medical materialism (p.14) and another on genius (p.18).
Cordeiro brackets the excerpts with maze-like images constructed of mirrored forms across four different colors. So we have the continua of mind to matter and of genius to madness embedded in a continuum of color and form (color and form merging).
Note the 18o° turn of the beige image in the upper left to be mirrored by the magenta image in the lower right.
Part 4, labeled “Section L: Notes on Seasonal Fluctuations of Lightweight Discrepancies”, is the densest of the gatherings. Drawings, verse typeset in English and scribed in Portuguese, typographic arrangements, trimmed and segmented photographs, and linocut prints of a stone wall all find their way into Part 4.
Note how the colors of the tulip shapes echo the colors of the maze in Part 3.
The “Epilogue” tells us, “The handwritten text in Portuguese is a word play with the alliteration afforded by that language between the verb to see and the season summer, and translates roughly as: ‘summer shall see gone that which / by going is now new being. / seeing such an hour at birth is to / be seen alive.” Another continuum.
“a shadow aside / a step askew / escape afloat in shape of arrows”. The segmented photos of an Upper West Side building’s fire escape articulate with the angled beam shape to echo the text.
The text before the concluding “end-on” image in this gathering introduces another continuum: “(Life begins at the end of your comfort zone.)”
Part 5, Section Z is the wrap-up, conflating the end of the alphabet with the end of the day (twilight), but of course, twilight is also a point on the continuum of day into night.
Lusco-fusco = twilight.
At this point, the reader might register that a continuum whose extremities hang in the balance against one another and yet are still connected is also a description of metaphor itself. Two disparate terms are brought together to make a figure of speech. Cordeiro brings two disparate objects together — a softcover codex and the shape of an angled beam, a hard form of structural support — to shape her artist’s book. She materializes that metaphor, then uses it as a platform for textual, graphical, material, and structural metaphors that celebrate the limp vellum structure. It is a striking accomplishment that challenges readers to think with their hands as well as their minds.

The folds and registration of images allow the viewer to find and create new shapes and color combinations. Its shapes and colors might remind viewers of Heinz Edelmann’s art for The Yellow Submarine. In its appeal to the child in the adult, it will remind book art enthusiasts of the works of Katsumi Komagata, Warja Lavater, Bruno Munari, and Peter and Donna Thomas. In its sophistication, it might remind them of the contributions to LL’Éditions leporello series.

First, the back-dating. This comes from the delightfully annoying or annoyingly delightful belated discovery of Erik Kwakkel’s 2015 entry on the history of the horn-book “Book on a Stick” in Medievalbooks. Delightful and annoying to find the truly earliest appearance of a horn-book right under my nose in the Bodleian Libraries but too late to include it in the Alphabets Alive! exhibition at the Bodleian in 2023.
Andrew White Tuer’s History of the Horn-Book (1897) came close with its dating of the horn-book’s first appearance as 1450, but as Kwakkel writes:
The image shows Christ being brought to school by his mother. He is bringing his “textbook” to class: a hornbook, which dangles from his wrist by a string, just like many of the later specimens did … Quite intriguingly, we are shown a real medieval snapshot of how children carried their hornbook to and at school. More importantly, it shows that the hornbook was indeed a medieval invention….While no actual hornbooks appear to survive from the medieval period, these visual representations show that educating young children was also the driving force behind the production of hornbooks in the age before print.
And for the updating, here is Ashley Thayer’s Mechanical Horn-book (2025) just arrived in the Books On Books Collection.
Mechanical Horn-book (2025) Ashley Rose Thayer Horn-book. On stand: H192 x W160 mm. Off stand: H192 x W115 mm. Unique. Acquired from the artist, 17 October 2025. Photos: Courtesy of the artist. Books On Books Collection.
The paddle is made of pine wood, the gears of vellum-covered bookboard, the spinning “arm” of authentic cow horn, and the wrist loop of embroidery thread by a medieval finger loop braiding technique. On dark grey-blue Khadi paper, Thayer has painted a border of the moon, a berried floral garland, and a wyvern, the heraldic emblem associated with Wessex, the Anglo-Saxon kingdom from which Alfred the Great emerged in the 9th century. On the reverse, a cross of cut red leather with five inserts of calligraphed vellum alluding to Christ’s five wounds reflects the horn-book tradition of combining religion with learning the alphabet. It also makes this horn-book reflective of Alfred’s Anglo-Saxon and Christian background.
The pointer, called an aestel in Old English, is made from poplar wood, an antique button, and antique bone. Its inclusion isn’t simply functional. Appearing alongside the Wessex wyvern, it points to that famous aestel on display at the Ashmolean in Oxford: the Alfred Jewel.

Making Memeries (2016) Lucas Blalock Board book consisting of nine 3mm thick card leaves with 8 double-page large colour photos, all of which interact with a down-loadable app. H330 x W210 x D28 mm.

How do we respond to an artwork of collage or assemblage that is missing a piece — assuming that we can tell ? And if all of the elements are ephemera, does it matter to our appreciation of it? Do we keep returning in annoyance to the gap — like a tongue to a missing tooth? Do we give up on it — like the purchaser of a secondhand jigsaw puzzle missing a piece or two? Or do we sigh and suppose appreciatively that the disappearance of an element of ephemera from a collage or assemblage of ephemera proves the artwork’s point?
Lucas Blalock is an artist of augmented realities. With the right device and app pointed at his artwork, we should be able to see images floating and moving over its surface or seemingly in the surface among its images or transforming them. According to the back cover, we can download this app from the iTunes App Store to interact with the book’s images. The app, however, was removed from the App Store in July 2023. Using the WayBack Machine, we can find the publisher’s announcement of the Making Memeries installation with Blalock in the Tate Modern’s Turbine Hall:
The London-based curatorial project Self Publish, Be Happy presents a programme of events that explore the blurring boundaries surrounding on/offline existence and distribution of photographs. The event, titled Making Memeries, will take place at Tate Modern during this year’s Offprint London art book fair from 20-22 May.
Artist Lucas Blalock has created an installation for the middle of the Tate Modern’s Turbine Hall that functions as a staging area for workshops and performances. The installation consists of a set of eight movable panels that display a new suite of photographs by Blalock. The elements of the installation, conceived of specifically for this project, can be further activated via this app, Making Memeries.
The audience will be able to immerse themselves in, and interact with the work through the app, which uses your camera to produce a digitally augmented reality. Blalock’s work has long been interested in the cohabitation of the worldly and the virtual behind the photographic surface, and this project has allowed the artist to picture this cohabitation on both sides of that plane. Blalock has collaborated with REIFY, the augmented reality (AR) creative studio, to build an experience that blurs traditional boundaries and challenges one’s expectations of viewership.
Photos from old website of Self Publish, Be Happy. Accessed 26 October 2025.
Among the performances facilitated by the installation was Anouk Kruithof’s Connection, which also contributed to the aim of blurring the boundaries of the physical and digital.
But without the app or memory of the installation, we have a gap like that missing tooth. We can bridge the gap somewhat with online links and the book’s collaged imagery of mixed media and photographs to recognize that Making Memeries is also about how we perceive surfaces and what lies beneath — and what might come between. Consider the earplugs alongside the telephone below. Then there’s the pair of spectacles in the shape of fingers that would cover the wearer’s eyes. Now look back to the cover, and we find the view from behind those finger-spectacles.

Or consider the images of the model of the epidermis with which the book opens and closes. ortunately, we have a YouTube link and Olga Yatskevich’s review to let us know that the “augmented reality radically changes the experience, making the image active rather than static – the app brings rounded depth to the model, shows blood running through the vessels, and allows us to explore the space around the object, its sides and the top”.

There’s something childlike, playful but serious conveyed in all this. Physically Making Memeries presents itself as an oversized children’s board book (or perhaps a board book for undersized adults). The use of the board book to make this cross-over can also be found in other artists’ books — Colleen (Ellis) Comerford’s ABCing and Phil Zimmermann’s Sonorensis, for example.
Fore edge of Making Memeries.
What the board book only partially conveys with the Connection link in hand, so to speak, is the intent expressed on the back cover and in the Tate’s announcement:
Making Memeries is set in a time when everyone has become a lifestyle photographer. It is still your life but the image production is decidedly public; and in that case temporary, verging on fleeting, because these public channels have so many content providers and, along with our attention spans, are in a perpetual state of refresh. [back cover]
Before the advent of the Internet the act of taking a photo was often intended to make memories; to store and preserve our past in still, printed images. In today’s digital age the act of taking photos can be enough for the photograph-taker. The act is exhausted by the process. This can be seen in the way a mobile phone camera offers immediate satisfaction — producing a file that may never be looked at again. Today a photo has a different claim to time, being much more in the “now” than in the “this has been” of its 19th and 20th century pre-internet forbearers. We, in turn, live in a culture of the perpetual present, in a meme-driven world where photos can effortlessly be shared, but where they most often disappear into digital oblivion. [Tate Modern announcement]
It feels ironic that Making Memeries‘s “missing tooth” is digital. The same year of Blalock’s installation at the Tate, Pokémon Go arrived, and people began wandering into traffic to capture Pokémon figures that their cameras projected onto the streets around them. Nine years later, the company owning the app has sold for $3.5 billion, and the world’s richest country is governed by meme. Is art miming life, or life miming art?

The ABC of Advertising is No. 205 in the RedFoxPress “c’est mon dada” series. The series name comes from the French expression meaning “it’s my thing”. Dada is also a colloquial child’s expression for “horsie” or “hobbyhorse”. So, of course, the French adopted it as the name for one of the avant garde movement of the early 20th century. Although you might think from The ABC of Advertising that wood type and letter press are Hans Witte’s “hobbyhorse”, it’s clear from his artist’s books, children’s books, and book object installations that he has a herd of them.

Marlene MacCallum achieves distinctive results by painting with photography and sculpting with book structure in her artist’s books. Her painting with photography has involved not only collage work but pinhole cameras, digital cameras, digital layering and masking as well as a variety of transfer processes — digital and analogue photogravure, lithography, digital pigment printing, and digital inkjet printing. Sculpting with book structure mainly includes varying the binding as in the accordion with fold-out of Obvert (1997), the tunnel book structure of Do Not Enter (1998), the gatefold of Domestic Arcana (1999), the tile format fold-outs of pink story (2004-05), the accordion of Quadrifid (2009), the dos-à-dos of Glaze: Reveal and Veiled (2013), and the Miura fold of Rise (2020). It also includes altering books as in Withdrawn (2010) and varying the substrate as in the lace paper, Moriki, double matte Mylar, Lanaquarelle, and embossed leather of Townsite House (2006) and the etched copperplate and Tyvek of Trompe l’Oreille (2011).

In 1900, in China’s Dunhuang province, the Diamond Sutra (868 CE), the world’s earliest complete and dated printed book, was discovered in a cave along with 40,000 scrolls. One of those other scrolls — Or.8210/S.6349 — was possibly just as important for the book arts as the Diamond Sutra was for the history of printing. Like the Diamond Sutra, Or.8210/S.6349 resides in the British Library and is “the only known example of whirlwind binding in the Stein collection of the British Library” (Chinnery). The structure is also known as dragon scale binding, although distinctions between the two have been debated (Song). It came into use in the late Tang dynasty (618-907 CE) then fell away in the face of the easier to handle butterfly and wrapped-back bindings. Besides Or.8210/S.6349, there are few surviving examples of original whirlwind or dragon scale bindings.
