Scene: the island of Salamis

The middle-aged poet Bion is the guardian of young Nysa whom he has freed from slavery. He welcomes the travellers Cratès and Agénor, a young philosopher and pupil of Plato, as guests in his house. Agénor and Nysa fall in love, although Nysa does so reluctantly as she believes she owes a debt of gratitude to Bion. Bion pretends to go on a journey, saying he plans to marry Nysa on his return. During his absence, Nysa and Agénor declare their love for one another and decide to marry. Bion suddenly reappears leading a child disguised as Cupid and interrupts the wedding ceremony. He teases Agénor by pretending that the celebrations are for his marriage to Nysa. Agénor, overcome with shame at betraying Bion's hospitality, prepares to leave, but Bion tells the young couple he has known of their love all along and has engineered events to test them. He gives his blessing to their marriage.
