They belong to a type of manuscript Lusitano-French, or Lusitano-Spanish planispheres, which is represented by several specimens, all of which are copies from a prototype which has either been destroyed or has not yet been found. As the original model, or prototype, is of a date anterior to 1536, they may be considered collectively notwithstanding the apparent later date of some of them.* [* Desliens' bears the date 1566; see pages 70-71.] The Australian portion, or Jave-la-Grande, of the oldest one, given here first, is taken from a large chart of the world, on a plane scale, painted on vellum, 8ft. 2in. by 3ft. 10in., highly ornamented with figures, etc., and with the names in French. At the upper corner, on the left hand, is a shield of the arms of France, with the collar of St. Michael; and on the right, another shield of France and Dauphiny, quarterly. It was probably executed in the time of Francis I. of France, for his son, the Dauphin, afterwards Henry II.; hence, this chart has sometimes been called the "Dauphin Chart."* [* Another of these planispheres, belonging to the same French School of Cartography, was presented to Henry II. of France. About that time a movement was set on foot for the colonisation of the Great Southern Continent, or Jave-la-Grande. The promotors failed in their endeavours, and one of them went to England with the hopes of better success; he also failed in his efforts, and the great colonising scheme was abandoned.] This chart formerly belonged to Edward Harley, Earl of Oxford and one of the principal Lords of the Admiralty, after whose death it was taken away by one of his servants. It. was subsequently purchased by Sir Joseph Banks, Bart., and presented by him to the British Museum in 1790. Copies of this and other maps of the same category, have been made for the Sydney, Melbourne and Adelaide Free Public Libraries, at considerable expense. This was a wise step on the part of our governments, for the strongest evidence of early discovery as yet brought to light is shown in the draughting of these old charts of Australia. Unfortunately, as I have said, they are all mere copies of copies, the first of which were more or less altered in outline and corrupted in nomenclature, from a prototype which has not yet been found. But, if the internal evidence of these odd charts clearly shows the original or originals to have been Portuguese or Spanish, one point of the question will be settled, and the Portuguese and Spanish will undoubtedly be entitled to the claim and honor of having discovered Australia. As to the matter of date, that is of less importance, and can be fixed approximately, for the discovery must have taken place at some period between the arrival of the Portuguese and Spanish in these seas and the draughting of the earliest known chart, that is between the years 1511 and 1536, a period of 25 years.*
