Timotheus of Gaza. A grammarian who lived in the reign of Anastasius at the end of the 5th century. He was a student of the Egyptian philosopher Horapollo (so the Cyrillus Lexicon). Tzetzes (Historiae 4.166- 69) remarks that Timotheos, along with Aelian and Oppian, represents the best zoology. The Suda (T 621) describes him thus:
Of Gaza. Grammarian. He lived under the emperor Anastasius, for whom he wrote a tragedy on the public tax known as the chrysargyros. He also wrote in epic verse On the four-footed animals in India, Arabia and Egypt, and the creatures of Libya; also on unusual foreign birds and snakes in 4 books.
The 4 books in epic verse on animals (De animalibus, peri zoon) seem to be entirely lost. But a manuscript from Augsburg (now in Munich) preserves an 11th century prose paraphrase of the work, but without indicating the author. The date of this paraphrase is clear from the section recording the arrival of a giraffe in the time of Anastasius, and the same “in our own time” under Constantine Monomachus. The creation of a prose paraphrase indicates the popularity of the work. The editio princeps was printed by Matthaei in Moscow in 1811, but most of the edition was destroyed by Napoleon’s attack on the city. Portions of the text in an Oxford manuscript were published by Cramer, and these give the name of the author. Older catalogues suggest that an incomplete copy of this work – or perhaps even of the original – may be found on Mount Athos, in the library of the Great Laura.
In addition some fragments of grammatical work Peri Syntaxeos were published by Cramer from a Paris manuscript (Coislin 387). The “tragedy” – probably, at this date, merely a speech or dramatization, was perhaps written at the request of his fellow townsmen as a petition against the hated chrysargyron tax. Seitz’s suggestion that the catalogue published by K.N.Satha indicates an “incomplete” copy of the tragedy on Mount Athos probably in fact refers to a copy of the De animalibus, as the title is only “to the emperor Anastasius; incomplete”.

The zoological handbook of Constantine VII Porpyrogenitus (Excerpta Constantini de natura animalium) is perhaps one of the most important Byzantine zoological works. It included excerpts from Timotheus of Gaza, Aristotle, Aelian and others, based mainly on the epitome of Aristophanes of Byzantium. Two books (out of four) survive under the title Συλλογὴ τῆς περὶ ζῴων ἱστορίας, χερσαίων πτηνῶν τε και θαλαττίων.
