, which would be colonised by France in 1630. The expedition was the only attempt by an Italian state to colonise the Americas.

The Amazon region had been previously visited by numerous European explorers and traders over the course of the preceding century. Robert Harcourt sailed for Guiana in 1608, establishing an English base on the Wiapoco River which lasted a few years. William Davies, a surgeon on the Thornton expedition noted that they expected to find the Amazon by sailing south from the West Indies until "...you shall see the Sea change to a ruddie colour, the water shall grow fresh, by these signes you may run boldly your course ."

Sailing from Leghorn in September 1608, Thornton returned to the same port in the end of June 1609, reportedly completing the voyage without losing a man. He brought back with him to Tuscany five or six natives

, most of whom died of small-pox. Only one lived on at the Medici court for several years, and learned to speak Tuscan. The natives often talked about the richness and fertility of their native land, speaking of a country rich in silver and gold. Thornton himself corroborated these reports, and asserted that the country was rich in rosewood, wild sugar canes, white pepper, balsam, cotton and many other kinds of merchandise which would form an abundant commerce for the Tuscans.

However, once back in Tuscany, Thornton found that Ferdinando I had died, and that his successor Cosimo II was uninterested in the establishment of a colony. Thornton was ready to sail back to the area between the rivers Orinoco
