This chapter argues that in Theocritus Idyll 7 Lycidas falls into none of the categories listed by Dover in his 1971 commentary (ostensibly a comprehensive list) but into a category he had overlooked, that of a fictional character from another poet’s work. This other poet, I suggest, was Philitas of Cos, whose very influential early Hellenistic poetry is known only from a few fragments and from later allusions and references. Among the many things explained by this hypothesis (and it remains only a hypothesis) are the Coan setting of Idyll 7’s narrative and the erotodidactic role of Philetas in Longus. The ‘Cydonia’ given as Lycidas’ origin becomes a Cydonia some kilometres north of Mytilene on Lesbos, arguably the hill-flanked coastal plain where Longus asks readers to imagine the estates on which Daphnis and Chloe pastured goats and sheep.
