#OTD in 1570.
Cartographer Abraham Ortelius issues Theatrum Orbis Terrarum, the first modern atlas.
Three Latin editions of this (besides a Dutch, a French and a German edition) appeared before the end of 1572; 25 editions came out before Ortelius' death in 1598; and several others were published subsequently, for the atlas continued to be in demand till about 1612. It is often considered as the official beginning of the Golden Age of Netherlandish cartography (~1570s–1670s).
