The rare first edition of Kino's 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…one of the last interesting large format California as an Island maps. 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 languages thereafter, and became one of the seminal 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. The last example was offered by the Map House in London in the Millenium Catalogue, for a substantially higher price. A fine example of this seminal work, an essential map for California Collectors.
