The Ulm edition of Ptolemy was first published in 1482 by Lienhart Holle. In contrast to the two earlier illustrated editions of Ptolemy's geography - Bologna (1477) and Rome (1478) - the maps in the Ulm edition are woodblock prints, not copperplate engravings. The maps in the Ulm edition follow the manuscript maps of Donnus Nicolaus Germanus, a Benedictine monk from Breslau who produced brilliant presentation copies for Italian elites in the 1460s and 1470s. Specifically, the Ulm was patterned after the manuscript atlas prepared for Pope Paul II. The Ulm Ptolemy was the first book Holle published, but it was also to be one of his last. Holle went bankrupt shortly after the original publication. The work was then taken over by Johann Reger, who issued another edition in 1486.

The differences between the two editions are relatively small.  The 1486 maps typically include titles at the top, whereas there were no titles on the 1482 maps.   An unpublished study of the individual maps reveals that there are multiple states of most of the maps.

It had long been suggested that the way to differentiate between the 1482 and 1486 editions was the use of lapis lazuli blue in the 1482 edition for the seas, whereas the 1486 used brown.  However, the same unpublished study, which evaluated dozens of examples of the two editions, determined that the earliest examples of the 1486 were also issued with the lapis lazuli blue, suggesting that when Johann Reger acquired the woodblocks, he likely also acquired some unused lapis lazuli.  In 2021, we offered for sale a complete example of a 1486 entirely in lapis lazuli blue.
