Giovanni da Verrazzano
In 1524, Francis assisted the citizens of Lyon in financing the expedition of Giovanni da Verrazzano to North America. On this expedition, Verrazzano visited the present site of New York City, naming it New Angoulême, and claimed Newfoundland for the French crown. Verrazzano's letter to Francis of 8 July 1524 is known as the "Cèllere Codex".
