Short answers, pulled from the story.
Bion of Smyrna lived in the ancient city of Smyrna during the late second or early first century BC. He is listed by the Suda as one of three canonical bucolic poets alongside Theocritus and Moschus.
An epitaph dedicated to Bion states that he was poisoned and implies he died at a young age. No other biographical facts survive from antiquity to confirm these brief accounts.
His surviving poetry includes his longest poem which spans ninety-eight lines and serves as a lament for the death of Adonis. Seventeen poetic fragments survive through medieval manuscripts with the remaining pieces ranging from single lines up to eighteen lines each.
Joachim Camerarius first attributed the long Lament to Adonis to Bion of Smyrna on the 15th of May 1530 after it had been transmitted anonymously. Modern scholars accept this attribution based on metrical similarities with known fragments and references found in Pseudo-Moschus' Epitaph for Bion.
Meleager of Gadara alluded to his work while Ovid and Catullus referenced themes similar to those found in Bion's verses. Greek novelists including Achilles Tatius, Longus, and Heliodorus incorporated elements of Bion's style into their own narratives.
