Hanno the Great may refer to any of three different leaders of ancient Carthage: According to B. H. Warmington, the nickname was probably a family name or a term not well understood by the ancient Greek or Roman writers.
[1] Gilbert Charles-Picard and Colette Picard assign the men Roman numerals to distinguish them: Hanno I the Great, Hanno II the Great and Hanno III the Great.
[2] Warmington does not use Roman numerals,[1] nor does Dexter Hoyos.
Hanno I is called magnus (Latin for "great") in the table of contents of Trogus' history.
Sometimes it taken to be a translation of the Punic title rab, meaning "chief", but this is unlikely.
