Bion of Smyrna, floruit in the 2nd century BCG, was a bucolic poet probably working a bit after the time of Theocritus. Very little of his work survives: seventeen fragments preserved by Stobaeus and the Epitaph of Adonis.
He writes in the Bucolic Doric dialect.
I use the numbering of Gow's OCT Bucolici Graeci.
