Pitys

A beautiful nymph who was loved by Pan and Boreas. When she chose Pan, Boreas blew her over a cliff. Gaea then took pity on her and turned her into a pine tree. When the north wind (Boreas) blows through the tree you can sill hear her weep.

According to another story Pan chased her and in order to get away from him Pitys turned herself into a pine tree. The tree then became holy to Pan, who made a wreath of pine branches to wear.
