He also studied at what is now the Academia Militar das Agulhas Negras and took a Medicine course and Philosophy. In 1831, he left Brazil along with Debret to Europe, in order to improve his painting techniques. In 1835, he went to Italy, where he met Gonçalves de Magalhães, another Brazilian poet. He and Magalhães would create in France, in the year of 1837, a short-lived magazine named Niterei, alongside Francisco de Sales Torres Homem.

He decorated the imperial palace in Petrepolis, the wedding of Pedro II with Teresa Cristina of the Two Sicilies and the aforementioned emperor's coronation.

Reuniting with Gonçalves de Magalhães and Torres Homem, he founded a periodic named Minerva Brasiliense, that lasted from 1843 to 1845. He would publish in this periodic his poem Brasiliana. In 1844, alongside Torres Homem, he founded the humoristic magazine Lanterna Megica, where he published his caricatures.
