Rare first edition of Kino's seminal map, which definitively ended the myth of California as an Island. Kino was a jesuit Missionary, who surmised that California was not an island long before his trip to Mexico. When he arrived, he initially transmitted information back to Europe which found its way into Scherer's maps and De Fer's Cette Carte. After obtaining permission to travel up the Gulf of California and explore the region, Kino was able to establish his theory that California was not an island. The first edition of the map was printed in one of the volumes of the Jesuit reports Lettres Edifantes. It was reissued in a number of editions and languages thereafter, and is one of the landmark California maps, although a number of commercial cartographers ignored the report for 20-30 years and continued to show California as an island. While later states of the map are available on the market, the first edition is rarely available. Slightly narrow right margin, as issued, else a fine example of this seminal work and an essential map for California Collectors.
