In Greek mythology, Mariandynus (Ancient Greek: Μαριανδυνός) was the eponymous hero of the Mariandyni tribe in Northern Anatolia. He was an Aeolian,[1] a son of either Cimmerius, or Phrixus,[2] or Phineus (and in the latter case, brother of Thynus).[3] He had several sons, of whom the eldest may have been Titias.[4]
Mariandynus was also the name of his grandson through Titias, who was credited with composing a mourning song in honor of his brother Priolaus, killed in a battle against the Bebrycians.[5]
