The author claims that the excessive employment of the term λλεεππττóóςς for characterizing Aratus' poetry and for denoting its conformity to the aesthetic ideal of Hellenistic poetry, as defined by Callimachus' poetic standards, stems from a misinterpretation, both by the later biographical tradition and the modern scholarship, of a number of poetic sources. λλεεππττοολλóóγγοοςς, in king Ptolemy's epigram ( SH 712), λλεεππττὴ φφρροοννττííςς in Leonidas' epigram ( AP 9.25), λλεεππττή in an acrostich of the Phaenomena, the title Tὰ κκααττὰ λλεεππττóóνν of an Aratean poetic collection, all mean quite different things, and are unrelated to Callimachus' Mοοῦσσαα λλεεππττααλλέηη. The reception in contemporary Alexandria court circles of the poetry of Aratus, the official encomiast of Antigonus Gonatas, archenemy of the Ptolemies, was not favourable. A black mark in the poet's record must have been a pun on his name (ἄρρρρηηττοοςς -- Ἄρρηηττοοςς), which he impiously inserted in the hymnic Phaenomena proem which praised Zeus. Theocritus, Id. 17.1 -- 4, criticized him indirectly, but Leonidas, AP 9.25, exonerated him from the blasphemy. This incident prompted the cancellation of the Jovian proem and the composition of a series of alternative proems to the Phaenomena. Callimachus' Ep. 27 is not a praise of Aratus, as was hitherto believed, but a mortifying criticism of Aratus' didactic epic. It is written in a bi-level satiric style hidden behind an innocent faççade, used also in Ep. 13, an epigram against Posidippus of Pella. It blames Aratus not for imitating Hesiod, but for imitating the worst verses of Hesiod's Works and Days. It also reverses Aratus' pun (Ἀρρήττοουυ ἀγγρρυυππννííηηςς -- ἀρρρρήττοουυ ἀγγρρυυππννííηηςς), in order to stress the bookish and laborious character of the Phaenomena. [ABSTRACT FROM AUTHOR]
