Marsilius is Italian, Latin in Origin.

Marsilius is the medieval Latin form of a name built on Mars, the Roman god of war, with the adjectival/gentilic suffix -ilius, giving the sense “of Mars” or “dedicated to Mars,” hence “warlike.” It parallels formations like Marcellus (“little Mars”) but preserves a more direct link to the theonym. As a learned Latin given name, Marsilius circulated in ecclesiastical and academic contexts, then filtered into Romance vernaculars.

The name is best known through figures such as Marsilius of Padua (political theorist, c. 1275–1342) and Marsilius of Inghen (scholastic philosopher, d. 1396), and appears in Old French literature as Marsile in the Chanson de Roland. Vernacular variants include Marsilio (Italian, also Spanish, rare), Marsílio (Portuguese), and Marsile (French). Related diminutives/nicknames may include Lio or Marsi in modern use. Though uncommon today, Marsilius and its variants appeal for their classical gravitas and clear martial meaning.
