For decades paleoslavists from around the world have known the inconspicuous, relatively small codex kept in the Ghent University Library in Belgium – the codex gandavensis slavicus 408 – as the book that was once commissioned and perhaps owned by Anna, the wife of Tsar Ivan Stratsimir (John Sracimir, r. 1356–96) who ruled over the Bulgarian secessionist principality of Bdin, present-day Vidin, as suggested by the colophon. In all probability, however, the colophon was copied in the fifteenth century – after the principality of Bdin had fallen to the Ottomans in 1396 – from a now lost original, together with the rest of the texts.
