The Cape of Palms that jutting land we name,
Already conscious of our nation’s fame.
Where the vexed wave’s against our bulwarks roar,
And Lusian towers o’erlook the bending shore:
From The Lusiad
The Lusiad recounts the great voyage of Vasco da Gama to India in 1497. It lists the places passed on the way. Guinea Bissau was one of the Portugese possessions in Africa.
