Gelius

Gelius is a Roman nomen gentile, or family name. It was relatively uncommon, particularly when compared to more widespread names like Julius or Cornelius. Members of the gens Gellia were of plebeian origin.

The most well-known individual bearing this name is Aulus Gelius, a Roman author and grammarian of the 2nd century CE, best known for his work Noctes Atticae (Attic Nights). This collection of miscellaneous anecdotes, literary criticism, philosophy, and antiquarian lore provides valuable insight into the intellectual life of the Roman Empire during the reign of the Antonine emperors.

The etymology of the name "Gelius" is uncertain. Some scholars have suggested a connection to the Latin word gelidus, meaning "frosty" or "cold," but this is speculative and not universally accepted.
