Thronia

In Greek mythology, the name Thronia (Ancient Greek: Θρωνία) or Thronie (Θρωνίη) may refer to:

Thronia, daughter of King Belus of Egypt, and the mother of Arabus, the eponym of Arabia, by Hermes.¹
Thronia, a Naiad nymph, mother of Abderus by Poseidon² and the eponym of the city Thronion in Opuntian Locris.³ Her father was possibly the river god Nestus in Bistonia⁴ and thus probably the sister of Callirhoe.⁵
