Second edition of the Spanish translation, published just two years after the original English edition (the first Spanish edition was published in the same year as the second). The work tells the voyage around the world of the English navigator John Byron (1723-1786) who, between 1764 and 1766, commanded the frigate Dolphin, accompanied by the frigate Tamer, through the Pacific Ocean, in search of new continents, having returned to England less than two years after his departure. The translator included at the end a “Resumen histórico del primer viaje hecho al rededor del mundo, emprendido por Hernando de Magallanes, e llevado felizmente á termino por el famoso capitan español Juan Sebastian del Cano”, with its own title page, next to page 176. In his work, Byron highlights the encounter with the giants of Patagonia, in Tierra del Fuego (represented in the engraving next to the title page), previously mentioned by the Portuguese navigator, but never scientifically confirmed. The fold-out map represents the Strait of Magellan in detail. Very clean contemporary binding copy, complete with flexible parchment. Palau, 38230. Borba de Moraes, p. 138.
