About the name
Cassius is Latin — the Roman family name traditionally read as "hollow" — worn by Caesar's lean conspirator, by three early saints, and by Cassius Clay before he became Muhammad Ali: a name that keeps choosing history's sharp edges.
Cassius has climbed into the American top 500 with the Roman revival, its -us ending now an asset rather than a museum label.
Cash is the effortlessly cool short form; Cass the gentler one. It pairs well with soft middles (Cassius James, Cassius Elio). On our vibe map it is Dark Academia's dueling society with Heirloom seals and Mythological reach.
