Aventinus of Alba Longa

In the surviving traditions Aventinus is presented as one of the kings in the Alban/Latial royal genealogies that link Aeneas and Lavinium to later Roman origins. Ancient commentators and later summaries report that he was buried or had a shrine on the hill later called the Aventine, and that he was succeeded in the king-list by Procas (father of Amulius). Ancient sources record competing etiologies for the hill-name — that it derived from the king Aventinus, from nesting birds (Latin aves), or from the Aventus river (a view attributed to Varro) — and present Aventinus as one etiological and genealogical figure within these overlapping accounts (see Servius; Livian summaries; later regnal chronologies).

Primary sources give no physical or iconic description of Aventinus; he is attested only as a named regnal figure in genealogical and toponymic contexts. Ancient commentators (e.g., Servius) discuss him as a king of the aboriginal inhabitants or as the Alban king buried on the Aventine, and some manuscript traditions conflate or distinguish an 'aboriginal' Aventinus from the Alban monarch in the regnal lists. Beyond statements that he was killed and buried on the hill or that he reigned for a stated number of years in regnal summaries, no corporeal attributes, dress, or pictorial iconography are recorded in the cited materials.

The cited traditions do not ascribe supernatural powers, magical functions, or hostile behaviors to Aventinus. He is represented in the sources in political/biographical terms typical of legendary kings: as a ruler who reigned (some summaries give an ordinal regnal length such as 'thirty-seven years' and chronologies place him in the 9th–8th centuries BC), as a successor in the Alban king-list (succeeded by Procas), and as associated with a burial or shrine on the Aventine Hill. No primary tradition records prodigies or abilities attributable to Aventinus himself; where prodigious events appear in surrounding narratives (for example, a predecessor struck by lightning) they relate to dynastic succession rather than to Aventinus's supernatural agency.
