# Diogo do Couto

Diogo do Couto (Lisbon, c. 1542 – Goa, 10 December 1616) was a Portuguese historian.

## Biography

He was born in Lisbon in 1542 to Gaspar do Couto and Isabel Serrão Calvos. He studied Latin and Rhetoric at the College of Saint Anthony the Great (Colégio de Santo Antão), an important Jesuit-run educational institution in Lisbon. He also studied philosophy at the Convent of Saint Dominic (Convento de São Domingos de Benfica) in Benfica.
In March 1559 (Armada of Pêro Vaz de Sequeira) he traveled to Portuguese India. As a soldier he took part in the Surat campaign in March 1560, living in Bharuch in 1563.
He returned to Lisbon with D. António de Noronha in 1569.
He was a close friend of the poet Luís de Camões, and described him in Ilha de Moçambique in 1569, as indebted and unable to fund his return to Portugal. Couto and other friends took it upon themselves to help Camões, who was thus enabled to take his most significant work, the Lusiads, to the capital.
Couto arrived in Lisbon on board the Santa Clara in April 1570, only to discover that the port was closed due to plague. Upon receiving permission from the King of Portugal (who he met in Almeirim), the ship docked in Tejo.
Shortly after Couto returned to Goa in the Armada of D. António de Noronha, he married Luisa de Melo and worked in a supply warehouse.
In 1595, Couto was invited to organize the Goa archive (being appointed "Guarda-Mor do Tombo da India") and to continue writing the Décadas (a history of the Portuguese in India, Asia, and southeast Africa) of João de Barros.
The 4th, 5th, 6th and 7th Décadas were published during his lifetime. After Couto died, his other works were in the hands of his brother-in-law, the priest Deodato da Trindade.
