How did Livy’s Latin prose style compare with Sallust’s style?

Livy and Sallust employed distinct approaches to Latin prose, reflecting their different literary goals and historical contexts.

Sallust sought to replicate the style of the Greek historian Thucydides within the Latin language. He achieved this through a "tortured" use of syntax and the incorporation of archaic and unusual vocabulary. While effective for his specific purposes, this style was often considered harsh and ill-suited for larger historical works.1

In contrast, Livy developed a highly varied and flexible prose style that the ancient critic Quintilian famously described as a "milky richness." Livy’s style was adaptable to the needs of his narrative:
* He utilized long, periodic clauses to set scenes.
* He employed terse, abrupt sentences to mirror rapid action.
* He used dry, formal language for archival facts, while shifting to a more dramatic and poetic vocabulary for battle descriptions and speeches.1

Ultimately, while Sallust’s style was characterized by a deliberate, sometimes harsh archaism, Livy’s prose was celebrated for its eloquence, fluidity, and ability to shift tone to suit the subject matter.1
