First Letter from North America to Europe: Amerigo Vespucci, 1502

The first known letter sent from the North American mainland to Europe was written by Amerigo Vespucci in 1502 — addressed to his patron, Lorenzo di Pierfrancesco de' Medici in Florence.

The Letter: Mundus Novus

• Written in Portuguese (Vespucci worked for Portugal) from Bezim (Brazil) or possibly the Caribbean
• Describes 1501–1502 voyage along South American coast (to ~50°S)
• Key claim: "We have found a New World... not an island but a continent"
• Published 1503–1504 in Florence, Venice, Paris, Antwerp — bestseller
• Martin Waldseemüller's 1507 map names the continent "America" after Vespucci

Historical Nuance

• Not the first European in NA: Norse (L'Anse aux Meadows, ~1000 CE); Cabot (1497); Columbus (1492, Caribbean)
• Not the first writing from NA: Norse sagas (oral→written 13th c.); Columbus's journal (1492, but Caribbean)
• First published account asserting a new continent: That's Vespucci's breakthrough
• North vs. South America: Vespucci explored South America; the name "America" later extended northward

Why It Mattered

Before Vespucci, Columbus insisted he'd reached Asia. Vespucci's letter—widely printed, translated, and mapped—shifted the European mental model: a previously unknown continent existed. That intellectual shift enabled the Age of Discovery's next phase.

The letter survives in multiple editions (Latin, German, Italian). The 1504 Mundus Novus (Venice) is the most accessible early print.
