ENUS, Enos, or Enum (anc. geog.), a town of Thrace, situate on the east-most mouth of the Hebrus, which has two mouths; and said to be built by the Cumans. It was a free town, in which stood the tomb of Polydorus, (Pliny); Enus is the epithet. Here the brother of Cato Uticensis died, and was honoured with a monument of marble in the forum of the Enii, (Plutarch); called Enii, (Stephanus); Livy says that the town was otherwise called Abysntus. Now Eno.
