Portuguese didactic poet, critic, and pamphleteer notable for his acerbity.

Macedo took vows as an Augustinian in 1778. Because of his turbulent character he spent much time in prison and was constantly transferred from one community to another. In 1792 he was unfrocked but obtained a papal brief that gave him the status of a secular priest. He was soon recognized as the leading pulpit orator of the day and in 1802 was appointed one of the royal preachers.

The best of his didactic poems are A Meditação (“The Meditation”) and Newton (1813). He also founded and wrote for a large number of journals, and the tone and temper of these and of his political pamphlets caused one of his biographers to call him the “chief libeler” of Portugal. His malignity reached its height in a satiric poem, Os Burros (1812–14; “The Asses”), in which he pilloried, by name, men and women of all grades of society, living and dead. From about 1823 he was the virulent champion of the absolutist reaction.
