The scribe of Harley MS 3686 was probably a mapmaker (based on the quality of the freehand drawings and the obvious spelling errors indicative of someone who did not thoroughly understand Latin). The scribe likely drew from other classical and contemporary cartographic references, such as the writings of
Pliny and another Ptolemaic codex written by
Andrea Bianco in 1436. Scholars of Ptolemy's work in Florence were humanists; neither scholars in
Genoa nor
Naples used the same cartographic systems displayed in the codex. These facts and the close parallels to Venetian Andrea Bianco's work determine this unknown cartographer was also from Venice. The unknown Italian cartographer that created the MS 3686 codex did add some improvements to his maps beyond making an exact replica of the copy from which he drew. This practice follows the broad rediscovery in Europe of classical knowledge and its use as the foundation of contemporary study. The cartographer cross-referenced Ancient Latin place names for areas around the Mediterranean and Western Europe with contemporary equivalents. The author also provided place names to areas unknown in Ptolemy's era (such as areas around the
Caspian Sea in Central Asia). Because of the author's apparent cartographic training, he redrew some of the maps to better conform to contemporary map-making practices. This codex improves on Ptolemy's
equi-rectangular and
orthographic projections but was written before the publication of the new
Mercator projection; re-creating and improving Ptolemy's regional maps without attempting to create a world map. ==Provenance==
