κολοφών

Colophon comes from Greek κολοφών (kolophōn), meaning 'summit, finishing stroke, crowning touch.' The word names Colophon, an ancient Ionian city in what is now western Turkey, south of Smyrna (modern Izmir). Colophon was famous in antiquity for its cavalry, which was of such high quality that it was said to tip the balance in any battle it joined — to add the Colophonian force was to add the decisive final element. From this reputation came the Greek idiom ἐπὶ κολοφῶνα (epi kolophōna), meaning 'to add the finishing touch, to crown a thing with its conclusion.' The term then transferred to the book world: the colophon was the scribe's or printer's note at the end of a manuscript or early printed book, the finishing stroke that completed the object and identified its makers. Adding a colophon was, etymologically, the cavalry arriving to settle the matter.

The colophon as a scribal practice predates printing by many centuries. Medieval manuscript scribes regularly added notes at the end of their work identifying themselves, the date of completion, the place of writing, and sometimes a prayer, a complaint about the difficulty of the task, or a request for the reader's prayers. These scribal colophons are among the most human documents in medieval book history: a monk in a cold Irish scriptorium in the ninth century writing 'the hand is tired, the vellum is rough, the ink is pale, the day is dark' before concluding his work. A Spanish scribe in 1454 noting that he finished the book at night, by candlelight, and praying that God reward him for the labor. These colophons give medieval manuscripts a personal dimension absent from their formal texts — the maker briefly visible behind the made thing.

When Johannes Gutenberg and his contemporaries invented moveable type printing in Europe in the 1450s, early printed books (incunabula) adopted the manuscript tradition of the colophon, typically placed at the end of the volume. The Mainz Psalter of 1457 — the first printed book to bear a date and printer's name — carried its information in a colophon rather than on a title page. The title page as a distinct feature developed gradually through the late fifteenth and early sixteenth centuries, eventually displacing the colophon as the primary site of publication information. The information migrated from back to front; the colophon was demoted from necessary to supplementary.

Modern books retain a vestigial colophon in the form of the printer's note sometimes placed at the very end of a volume — particularly in fine press editions and limited print runs, where the colophon might specify the typeface, the paper stock, the print run size, and the names of those responsible for the book's physical production. In typography and book design, 'colophon' has become a term of art for this final identifying note, used by publishers who want to signal attention to craft. The finishing cavalry still arrives, though in smaller numbers.
