A notion may be formed of the knowledge possessed by the Spaniards in the middle of the sixteenth century, on the part of the world on which we treat, from the following extract from a work entitled, “El libro de las costumbres de todas las gentes del mundo y de las Indias.” Translated and compiled by the Bachelor Francisco Themara. Antwerp, 1556. “Thirty leagues from Java the Less is Gatigara, nineteen degrees the other side of the equinoctial towards the south. Of the lands beyond this point nothing is known, for navigation has not been extended further, and it is impossible to proceed by land on account of the numerous lakes and lofty mountains in those parts. It is even said that there is the site of the Terrestrial Paradise.” Although this was not originally written in Spanish, but was translated from Johannes Bohemus, it would scarcely have been given forth to the Spaniards had better information on such a subject existed among that people. It has been already stated at pages xvii and xviii of this Introduction, that in the early engraved maps of the sixteenth century, there occur apparent indications of Australia, with names and sentences, descriptive of the country so represented, derived from the narrative of Marco Polo, with an intimation that some of these representations may not have emanated solely from that narrative. The earliest of these occurs on a mappemonde in the third volume of the polyglot bible of Arias Montanus, and the indication of Australia there given is the more striking that it stands unconnected with any other land whatever, and bears no kind of description. It is simply a line indicating the north part of an unexplored land, exactly in the position of the north of Australia, distinctly implying an imperfect discovery, but not copied from, or bearing any resemblance to, any indication of the kind in any previous map with which the editor is acquainted. In Thevet’s _Cosmographie Universelle_, Paris, 1575, is a map with Taprobane, La Grand Jave, Petite Jave, Partie de la Terre Australe; and in tom. i, liv. 12, the following passage: “L’art et pratique du navigage est le plus pénible et dangereux de toutes les sciences, que oncques les hommes ayent inventées, veu que l’homme s’expose à la mercy des abysmes de ce grand ocean, qui environne et abbreuve toute la terre. Davātage, avec ceste Esquille lon peult visiter presque toute ce que le monde contient en sa rotondité, soit vers la mer glaciale, ou les deux poles, et terre Australe, qui n’est encor comme ie croy descouverte, mais selon mon opinion d’aussi grande estendue que l’Asie ou l’Afrique, et laquelle un iour sera recherchée par le moyen de ce petit instrument navigatoire, quelque long voyage qui y peust estre.”
