The Voyage of Bran 

The Voyage of Bran is a classic of Irish literature. The story follows Bran mac Febail on his quest to the Otherworld, the realm of the deities. One day while Bran is walking, he hears beautiful music, so beautiful, in fact, that it lulls him to sleep. Upon wakening, he sees a beautiful silver branch in white bloom in front of him. He returns to his royal house, and among his retinue he spots a strangely dressed Otherworld woman, who identifies the branch to be from an apple tree growing in land of Emain and proceeds to sing a poem describing this Otherworld… This medieval narrative dates from the late 8th-century.
