, with an additional information that the maps are made of parchment. The maps of the ''Tratado'' clearly date from after 1514. For instance, it shows the Magellan Strait or Japan (which was only reported by the Portuguese in 1543). On the other hand, the position of certain Portuguese flags is not consistent with historical events; in particular in one of the charts, Portuguese castles are drawn in Inca territory, something that was never reported in any official document. Based on the presence of Japan, Armando Cortesão dated the atlas as "circa 1560", while other authors date it to "circa 1550".
