First Printing of Domingo del Castillo's 1541 Map of Baja and the West Coast of Mexico

Fine example of Domingo del Castillo's map of Mexico, which appeared in Lorenzana's Historia de Nueva-España, escrita por su esclarecido conquistador Hernan Cortes, aumentada con otros documentos, y notas, por el Ilustrissimo Señor Don Francisco Antonio Lorenzana, Arzobispo de Mexico.

Domingo del Castillo's manuscript map of 1541, as reproduced by Lorenzana in 1770, was the first map to establish definitively that California was in fact a peninsula and not an island. Originally drawn during the Alarcon Voyage to California in 1541. Castillo's map has been called "the oldest and most interesting cartographical document on California which we have." As noted by J.G. Kohl in his Descriptive Catalogue of those Maps, Charts and Surveys Relating To America Which Are Mentioned in Vol. III of Hakluyt's Great Work (Washington, 1857):

Two of the principal early exploring expeditions of the gulf and peninsula of California were undertaken by Francisco de Ulloa (1539) and Fernando Alarcon, (1540,) of which the first was sent out by Hernan Cortes and the second by the Viceroy of Mexico, Mendoza, Cortes's successor in command. . . .

The . . . voyage under Alarcon ranged like the first along the eastern and western shore of the inner gulf, ascertaining better then Ulloa the nature of the northern end of the gulf and of exploring the great river Colorado, which he asserts to have sailed up for eighty-five leagues.

Both Ulloa and Alarcon appear to have made a very good survey and research. Both were accompanied by good pilots-Ulloa by one Juan Castillo* and Francisco Preciado, who wrote the report on this voyage of Alarcon by one Nicolas Zamorano, his Piloto Mayor and "Dominico del Castillo," which latter made the chart to that voyage, of which we will speak instantly. The reports on both voyages are so ably and clearly written as few journals of that time . . . The report on the second voyage is written by the Commander Alarcon himself. Both were printed for the first time in Ramusio, from which Hakluyt took them. . . .

The original charts of both voyages are, however lost to us. But the pilot of the second or Alarcon's expedition, Dominico del Castello, as he is called in Hakluyt, or " Domingo del Castillo," as he calls himself, compiled after the second voyage, in the year 1541, in Mexico, a little chart of the visited coasts, for which he appears to have used the sketches and materials collected on both voyages.

This chart was preserved and hidden for a long: time in the archives of the descendants of Cortes, until, after the middle of the eighteenth century, the Bishop Lorenzano found it there, copied it, and published an engraving of it in his well-known work on Mexico. It has the following inscription: " Domingo del Castillo, Piloto, me fecit en Mexico aiio del Nacimiento de N. S. Christo de MDXLI." (Domingo del Castillo, pilot, made me in Mexico in the year of the birth of our Saviour, 1541.)

This chart is particularly rich in names on the eastern shore of the Gulf of California, or on the coasts of Mexico, Cinaloa, and Sonora.

[Alarcon] sounded there, measured distances, and observed the geographical position, and probably made a large special map of it.

He requested there even an intelligent Indian, with whom he conversed, "to set him downe in a charte as much as he knew concerning that river;" "which this Indian did willingly."

In our little general sketch these parts have been treated very generally. That, however, the charts of Arlacon were used is evident from the circumstance that two principal branches of the Rio Colorado have received the names "Rio de Buena Guia" and " Brazo de Miraflores," names which do not occur in Ulloa's reports, but only in that of Alarcon.

Castillo puts down upon his chart the northern end of the Gulf and the mouth of the Rio Colorado under about 34° N. L., in harmony with Alarcon's observation, who says about this in his report the following:

"By the situation of the river, and by the height -which I took, I finde that that which the masters and pilots of the Marquesse (Ulloa, Cortes's captain) took is false, and that they were deceived by two degrees, and I have sayled beyond them above four degrees."*

According to this, I said, Castillo puts down the northern end of the Gulf in 34° N. L. This is more than two degrees higher than the true latitude which we have on our present maps; and if, as it appears from Alarcon's journal, Ulloa had this latitude, he must have been a much better observer, and we must regret it so much more that we do not possess at present his original charts.

It is to be observed that there is a spirit of boasting in the reports of Alarcon, and that there was a feeling of emulation and envy between him and his predecessor, Ulloa, naturally growing out of the circumstance, that they were sent upon the same errand-" to find out the secret of the Gulf." This invidious feeling was probably still enhanced by the other circumstance that Ulloa was commissioned by Cortes and Alarcon by Mendoza, the successor and. in a certain degree, opponent of Cortes. Alarcon wished to surpass Ulloa in every respect.

The coast of the peninsula of California towards the main ocean, which was not seen at all by Alarcon, is put down in Castillo's chart after the charts of Ulloa. We find here the names "Punta de la Trinidad," "Pto de Senabad," "the islands of St. Estevan," of which one was the Island of Ceders, (Isle de Cedros,) to which on our chart is written the name " Pto de reparo," (the harbor of careening or caulking,) because Ulloa repaired and caulked there one of his ships and the "Cabo del Engaiio."

The latitudes are in this part of the chart much too low. The St. Stephen's islands are put in the latitude of 26,° whilst they stand in 27°; and the Caho del Engano is put in 27°, whilst Ulloa appears to place* the cape which he called so in 30° 31". The same invidious and boasting feeling which induced Alarcon and his pilot (Castillo) to extend the interior of the Gulf, which they considered to be their own discovery, two degrees further to the nor th, induced them probably also to bring the ne plus ultra of Ulloa further down to the south.
