Query: "Os Lusiadas" is one of the greatest epic poems

"Os Lusiadas" is an epic account of Vasco Da Gama's first sea voyage to India. It is written in the same style as the classic poems of antiquity and it elevates the Portuguese spirit of discovery and bravery to pinnacles of achievement. The Portuguese version is hard to read, but the English translation is in prose and is a delightful story with great historical significance. The title means "The Portuguese" sons of Lusos, brother of Romulus, and mythical founder of Lusitania.
