One of the Earliest Obtainable Sea Charts of the Texas, Florida and Gulf Coasts
Rare fourth state of Van Keulen's map of the Gulf Coast, from Florida and Texas to the Yucatan.
Gerard Van Keulen's map of the Gulf Coast is a landmark coastal charts of Texas and the Gulf Coast, extending to just east of Pensacola Bay. Martin & Martin notes that the Van Keulen chart of the Gulf Coast represented the most sophisticated rendering of the Gulf Coast to date. This fourth state continues the process of significantly revising the coastline, especially in Florida, the Gulf Coast and Texas, as demonstrated by a comparison to the earlier states of the map by Johannes Van Keulen:
As can be seen in comparing the two maps, the later editions add dozens of new place names and significantly re-works the coastal details, primarily from information derived from the Spanish. Other than the title, this 4th state bears little resemblence to the earlier editions of the chart.
The map shows dozens of place names along the coast of Texas, Louisiana, Mississipi, Alabama and Florida, along with detailed soundings. Fortifications are shown at Pensacola, F. Anconbazo, Pascagoula, Fort Bilocci (Biloxi), Mexicano (near Cap Delnarte) and several places near the mouth of the Mississippi River, along with Matos de Salvador. Several compass roses, rhumblines, ships at sea and other decorative features.
The Van Keulen family followed the Blaeu family as the official sea chart makers of the Dutch East Indies Company. Their charts are of paramount importance in the development of Marine Cartography. The fourth book of the Van Keulen Zee-fakkel, dedicated to the Americas, is one of most important of all American cartographic works, substantially updating and improving all then existing compilations on the coast of the Americas .
