Sam Andrew & Apollonius Rhodius 
Argonautica 

Apollonius of Rhodes, (born c. 295 bc), Greek poet and grammarian who was the author of the Argonautica. The two lives contained in the Laurentian manuscript of the Argonautica say that Apollonius was a pupil of Callimachus; that he gave a recitation of the Argonautica at Alexandria; and that when this proved a failure he retired to Rhodes. The first life adds the detail that the poet was still an adolescent when this happened, though it had previously said that he turned late to writing poetry. Both lives say that the Argonautica was well received in Rhodes, and the second cites a report that Apollonius returned to Alexandria and was appointed chief librarian. Another work has him succeed Eratosthenes in this post. But in a list of Alexandrian librarians on a late 2nd-century-ad papyrus (Oxyrhynchus Papyrus 1241), Apollonius succeeds Zenodotus and precedes Eratosthenes. If this evidence is accepted it may be conjectured that Apollonius became librarian about 260 bc and continued as such until about 247, when he fell out of favour under the new king, Ptolemy Euergetes, and retired to Rhodes. The traditional story of his quarrel with Callimachus was probably an ancient invention.
