A minor source on the discovery of America

TLDR: The sixteenth century poemDe navigatione Christophori Columbi by L. Gambara (1496-1586?) is compared with contemporary sources on C. Columbus's discoveries in order to verify whether C.Columbus through Nicolas Perrenot de Granvelle (1486-1550) and his son, the Cardinal Antoine (1571-1584), was the source of the poem, as stated on thededicatio.

Abstract: The sixteenth century poemDe navigatione Christophori Columbi by L. Gambara (1496–1586?) is here compared with the contemporary sources on C. Columbus's discoveries in order to verify whether C. Columbus through Nicolas Perrenot de Granvelle (1486–1550) and his son, the Cardinal Antoine (1571–1584), was the source of the poem, as stated on thededicatio. It seems that L. Gambara drew the historical events mainly from P.M. d'Anghiera and F. Columbus. However he added some new elements and an interesting early sixteenth century map of Columbus' discoveries (1st to 3rd voyages), probably all collected by Nicolas Perrenot de Granvelle. HenceDe navigatione (…) may be considered a minor source on Christopher Columbus discoveries.
