Two surviving portolan charts define the legacy of the Majorcan mapmaker Guillem Soler. Active during the late 14th century, Soler operated as a master instrument-maker and mapmaker, producing nautical tools that documented the Mediterranean, Black Sea, and Atlantic coastlines. His work remains a primary reference for the technical evolution of cartography within the Majorcan school.
Historical Context and Identity
Records place Soler in Majorca by 1368, and he was deceased before 1402. Although some past historians misidentified him as an Italian named Guglielmo Soleri, contemporary analysis classifies him as a citizen of Majorca of likely Catalan origin. He is distinguished as one of the few non-Jewish contributors to the Majorcan cartographic school of that era. In 1387, King John I of Aragon identified Soler as a Christian master possessing technical skills comparable to those of the cartographer Abraham Cresques.

Soler authored two primary charts. The first, from circa 1380, is held by the Bibliothèque nationale de France in Paris. It follows the traditional Majorcan style, featuring inland details like mountain ranges, rivers, and heraldic shields. Notably, it contains an early depiction of the English royal arms quartered with the French royal arms. The second chart, dated 1385 and held by the Archivio di Stato di Firenze, displays a shift toward the Italian school. It focuses on nautical utility, omitting most illustrations and interior geographical features.
Attributed Works and Family Lineage
Beyond his two signed charts, scholars attribute a third, smaller fragment to Soler. This 21x31 cm piece, held in a private collection, covers a portion of the western Mediterranean and is believed to predate his other documented works. His family continued this tradition of mapmaking: he is considered the father of Joan Soler and the ancestor of later cartographers Rafel Soler and Gabriel Soler, as well as the potential grandfather of the mapmaker Rafel Lloret.
