Olavo Brás Martins dos Guimarães Bilac, known simply as Olavo Bilac, was a Brazilian Parnassian poet, journalist and translator. Alongside Alberto de Oliveira and Raimundo Correia, he was a member of the "Parnassian Triad". He was elected the "Prince of Brazilian Poets" in 1907 by the magazine Fon-Fon. He wrote the lyrics of the Brazilian Flag Anthem.
Bilac, c. 1895
A sonnet is a poetic form that originated in the poetry composed at the Court of the Holy Roman Emperor Frederick II in the Sicilian city of Palermo. The 13th-century poet and notary Giacomo da Lentini is credited with the sonnet's invention, and the Sicilian School of poets who surrounded him then spread the form to the mainland. The earliest sonnets, however, no longer survive in the original Sicilian language, but only after being translated into Tuscan dialect.
