Hedylus (Ancient Greek: Ἥδυλος, Hḗdylos; fl.
3rd century BC) was a Greek epigrammatic poet of the Hellenistic period.
In some he describes the dedicatory offerings in the temple of Arsinoe, among which he mentions the hydraulic organ of Ctesibius.
Besides this indication of his time, we know that he was the contemporary and rival of Callimachus and friend of Poseidippus of Pella.
He lived therefore in the reign of Ptolemy II Philadelphus, and is to be classed with the Alexandrian school of poets.
