[1] He gave this land the name het Landt van d'Eendracht, literally Eendrachtsland, after his ship, the Eendracht (English: "Unity"[1] or "Concord").
[3]: 119 T.Lant van Eendracht also appeared on the world map, Nova Totius Terrarum Orbis Geographica ac Hydrographica Tabula by Jodocus Hondius II, published in Amsterdam in 1625, and on the world map by Johannes Kepler and Philipp Eckebrecht, Noua Orbis Terrarum Delineatio Singulari Ratione Accommodata Meridiano Tabb.
To the question, how far it was held to extend, I answer that in the widest sense of the term ('t Land van Eendracht or the South-land, it reached as far as the South-coast, at all events past the Perth of our day)
More to southward we find in the chart of 1627 I. d'Edels landt, made in July 1619 by the ships Dordrecht and Amsterdam, commanded by Frederik De Houtman and Jacob Dedel.
To the north of Dedelsland the coast is rendered difficult of access by reefs, the so-called (Frederik De) Houtmans-Abrolhos (now known as the Houtman Rocks), also discovered on this occasion.
[1] By the mid to late 1620s the Dutch had gathered a good deal of information, enabling them to chart the west coast of what had become known by then as Eendrachtsland with some accuracy.
[1] Heeres then suggests that the mid seventeenth century navigators were constantly faced by the problem of the true character of this South-land, asking themselves the question: ...was it one vast continent or a complex of islands?
Tasman and Visscher did a great deal towards the solution of this problem, since in their voyage of 1644 they also skirted and mapped out the entire line of the West-coast of what since 1644 has borne the name of Nieuw-Nederland, Nova Hollandia, or New Holland, [charting] from Bathurst Island to a point south of the Tropic of Capricorn.
