sented the continent of America. Their relations to Missouri 
cartography are, of course, only of a general nature ; but it is 
thought that they are of sufficient historic interest to justify a 
description of some of the more important ones here. 
Rough attempts at the mapping of America began almost 
with its discovery and we find the general outlines of the con- 
tinent suggested in charts dating back as far as the beginning 
of the 16th century. 
The map accompanying the edition of Ptolomeus of 
1508, edited in Rome, is credited with being the most com- 
plete and reliable extant of what was then known in regard to 
America.* The title of the map translated is, ‘* A more uni- 
versal table of the known world compiled from modern observ- 
ations.’’ It contains, of North America, little more than a 
rough and generalized outline of the eastern coast as far south 
as Florida. 
Columbus had entered the Gulf of Mexico but only ex- 
plored its southern coast. The ‘* Admiral’s map”’ in the 
Ptolemy, edition of 1513, shows a delta of a river correspond- 
ing in position to that of the Mississippi; but this must have 
been from conjecture, as it was not until 1518 that the north- 
ern coast was completely explored by Garay, who reached 
the Mississippi river and gave to that stream the name Rio del 
Espiritu Santo (River of the Holy Ghost). 
A Globe in Frankfort on the Main, in the city library, is 
credited to the year 1515 or 1520, and is supposed to have 
been made by J. Scheener, whose globe of the latter year 
preserved in Nuremburg agrees with this in all its principal 
features.t This map represents the North American continent

Winsor, in Vol. II of his Narrative and Critical History of America, on 
p. 218, gives a sketch of a map of the date 1520, which he states was sent to 
Spain by Garay, the Governor of Jamacia. It shows what seems to be the 
mouth of the Mississippi under the name ‘‘Rio del Espiritu Santo.” 
Winsor characterizes it as a “ surprisingly accurate draft of the shores of 
the Gulf.”’ .
