Which literary figure is known for the phrase "Veni, vidi, vici"?

The phrase "Veni, vidi, vici," which translates to "I came, I saw, I conquered," is famously attributed to Julius Caesar. He reportedly used this expression in a message to the Roman Senate following his swift victory at the Battle of Zela in 47 BCE. This phrase encapsulates not just the military success but also Caesar's confident and decisive approach to leadership, highlighting his ability to achieve rapid victories.

The other figures mentioned, such as Catullus, Cicero, and Sallust, were prominent in Roman literature and history but are associated with different works and ideas. Catullus is known for his lyric poetry, Cicero for his philosophical and rhetorical writings, and Sallust for his historical accounts. None of them are linked to the iconic phrase that characterizes Caesar's assertive and triumphant nature, making Julius Caesar the correct answer in this context.
