Aventinus of Alba Longa

Aventinus (said to have reigned 854-817 BC),[1] one of the mythical kings of Alba Longa, who was buried on the Aventine Hill later named after him.

He is said to have reigned thirty-seven years, and to have been succeeded by Procas, the father of Amulius.

Servius, in analysing Virgil's Aeneid, Book vii.

656, speaks of an Aventinus, a king of the aboriginal inhabitants of Rome, who was killed and buried on the hill afterwards called the Aventine Hill.

This king may be conflated with this one or with a separate figure in the Aeneid:
