Divna Manolova, Fabio Acerbi, Inmaculada Pérez Martín

Research output: Contribution to journalArticlepeer-review


The article presents the edition and a detailed discussion of an anonymous treatise of elementary arithmetic that served as the source of the so-called Letter to Khatzykes authored by the Byzantine scholar Nicholas Artabasdos Rhabdas. An updated survey of the extant evidence about the logistic treatises composed in the Nicaean period and in the early Palaiologan era, and a discussion of the prima facie surprisingly widespread phenomenon of appropriation of scientific treatises written by other contemporaries in late Byzantine times will also be provided.
