[1] Supposition based on internal evidence in two epigrams: c.m. 19.3 and c.m. 22.56f.; Sidonius claims that Claudian was from Canopus but for Sidonius this is probably a poetic term for Egypt. John the Lydian calls him a "Paphlagonian" but perhaps in the Aristophanic sense of "blusterer"; see the parallel usage in Procopius, Secret History 16.7.
[2] (Ms F, Adler reports, omits 'latter-day' and indeed everything after 'epic poet'.) Claudian also composed Latin invectives, panegyrics, and occasional poetry, all in either hexameters or elegiacs. A fragment of a Greek Gigantomachy also survives. See web address 1 for texts.
[3] Flavius Arcadius, elder son of Theodosius I (theta 144); he ruled the eastern Roman Empire (383-408) -- see OCD(4) s.v. Arcadius(2).
[4] Honorius, younger brother of Arcadius: see omicron 405.
