Life The author of the Astronomical Treatise (Ἀστρονομικὸν σύνταγμα) is anonymous. No biographical details survive. The work is dated between the 2nd and 6th centuries CE based on its content and technical Koine Greek, which reflects the astronomical traditions of the Roman Imperial period [1].

Works The sole extant work is the Astronomical Treatise (Ἀστρονομικὸν σύνταγμα). Preserved in a single manuscript (Vaticanus graecus 1056), it focuses on computational methods for determining the positions of the sun, moon, and planets [1].

Significance This treatise is a key example of Greco-Roman practical astronomy, distinct from more theoretical works. It illustrates the procedural methods used for astronomical calculations during the Roman era, representing a strand of maintained technical knowledge. Its survival in a single manuscript underscores the fragmentary transmission of such specialized texts [1].
