Marbling and Book-Matching
From the Pantheon to the Eye Tracker
Since Roman antiquity, builders have sawn blocks of veined marble into consecutive slabs and mounted them as mirror images, opened like the pages of a book. Book-matching imposes symmetrical order on the stone, yet because the veining changes from slab to slab the symmetry is always irregular. The technique, which Rosenberg (2025a) names opus sectile symmetricum and traces to Rome around AD 100, reappears in Byzantium, in early Islamic mosques, in Venice and in Baroque Rome, and it is ubiquitous today. When and why was it adopted, and what does its irregular symmetry do to the eye and the judgement of the viewer?
The question joins two lines of research: the history of abstraction and chance images (Rosenberg, 2007), and the amimetic aesthetic of marbling (Rosenberg, 2021), in which a stone's colours and forms are enjoyed as such, alongside the mimetic reading that discovers faces and figures in them. Book-matched marble is the exemplary case for confronting art-historical insight with the results of psychological experiments, and the lab has published on it continuously: on the history of taste behind the technique, on eye-tracking experiments with mirrored stone, and on the two kinds of perception it invites. The most recent chapter (Rosenberg, Kamencek & Long, 2026) grew out of the study days Il marmo come dispositivo / Marble as Device at Palazzo Barberini and the Galleria Borghese in Rome (2024), whose proceedings appeared as Il marmo in azione / Marble in Action in 2026.
The art-historical hypotheses are tested in a series of eye-tracking experiments, from marbled papers to book-matched stone. Further experiments are in planning, including book-matched wood and cross-cultural aspects.
