 In making his terrestrial globes , Molyneux examined <unk> ( instructions for directions at sea ) and pilots ( navigational handbooks ) . He is known to have given a <unk> for Brazil and the West Indies to Thomas Harriot in 1590 . He also received advice and assistance from navigators and mathematicians . It is likely , for instance , that Sir Walter Raleigh advised him on a legend in Spanish about the Solomon Islands that appeared on the terrestrial globe . Raleigh came by the information from Pedro Sarmiento de Gamboa , a Galician explorer sent by King Philip II of Spain to fortify the Strait of Magellan after Francis Drake had passed through it . In 1584 , the Spaniard was Raleigh 's guest in London for a few weeks , after being captured by Raleigh on a journey to Europe .
