Portugal's leading satirical poet of the 18th century.

At age 20 Tolentino entered the University of Coimbra to study law; he interrupted his studies three years later to become a teacher of rhetoric. In 1776 he was appointed to a post in Lisbon and the following year was named professor of rhetoric. About 1777, Tolentino grew tired of his teaching and aspired to public office. He dedicated numerous verses to members of the new political generation and, like other poets of the period, drew satirical sketches of the former minister, the Marquês de Pombal (A Quixotada). He eventually was made an officer in the royal administration. In 1790 he was made a knight of the royal family, and in 1801 his works were published by the state.

Tolentino's literary importance is based on the wide range of social types depicted in his poetic vignettes and on the light he sheds on the writer's position in Portuguese society from Pombal's reign to the end of the century.
