verse beg. Seithenhin saw de allan

  • verse

A series of nine Early Welsh englynion which elude to a legend about the inundation of Maes Gwyddno, ‘Gwyddno’s plain’, possibly in what is now Cardigan Bay or the Conway estuary. The disaster is said to have happened after a fountain-cupbearer (finaun wenestir) known as Mererid neglected her duty of guarding a certain well, which was subsequently allowed to overflow and submerge the land.
