Calydnus
Appearance
In Greek mythology, Calydnus or Kalydnos (Κάλυδνος) was a son of Uranus and the first mythological king of Thebes, after whom the city was thought to have been called Calydna[1]. He was believed to have built the first fortifications of the city, which was why Thebes were sometimes referred to as the "citadel of Calydnus". Calydnus was succeeded by Ogygus[2].
A certain Calydnus was also the mythical eponym of the island Calydna near Troy[1][3].
