Abstract
Aratus’ Phaenomena calls upon its reader to scrutinize the letters of the text as carefully as the stars and constellations that form its subject matter. The poem abounds with clever letter-play and wordplay, and its reception too is characterized by verbal cleverness, as later authors vie with Aratus and one another to create ingenious textual effects. Among the best-known examples is the word ἄρρητον at Phaen. 2, a witty hidden sphragis for Aratus, who nowhere in his work directly names himself. Later poets picked up on this pun: Callimachus speaks of the λεπταὶ ῥήσιες Ἀρήτου, repeating the verbal root of ἄρρητον in ῥήσιες and its sound in Ἀρήτου. Leonidas of Tarentum meanwhile rates Aratus ‘second after Zeus’, acknowledging the hidden sphragis, which follows directly after the invocation of Zeus in line 1 of the Phaenomena.
