Manuscripts
This significant Spanish derrotero contains 149 charts depicting the West Coast of the New World from Mexico to the Straits of Megellan. In addition, this manuscript has no chart titles or index. This derrotero was once thought to be that captured by Bartholomew Sharpe and used as the basis for William Hacke's atlas (see mssHM 265). However a close comparison of the charts with those of the Basil Ringrose atlas (based on the derrotero captured by Captain Henry Morgan) and the Hacke atlas indicate that this derrotero was not the principal source for Hacke's work. It appeared likely that this copy was the one captured by Morgan in a 1671 raid on Panama. Textual and material research carried out in 2024 by Juliet Wiersema, now suggest that the manuscript is an English copy of a derrotero held in the Society of Antiquaries of London (Ms. 221). Consistent spelling errors and watermark evidence strongly support an English, not Spanish origin. See: Wiersema, J. (2026). Farewell South Seas! Captured Spanish derroteros or English-made Copies?
