m Roman Mythology……… In Roman legend Romulus and Remus, the twin sons of Rhea Silvia and the God, Mars, were the founders of Rome. Sindarin: (city {of the} twins) Ost’wanun; m Ost’wanunion; f Ost’wanuniel.

(In Sindarin, ‘ost’ has two connotations: 1. city/town with a wall around it, 2. fortress/stronghold made or strenghtened by art.) The 2nd seemed to fit well for Rome.)●
