The latter were known to be active in the Black Sea and the Asian trade, e.g. in 1340, Pope Benedict XII speaks of receiving a Petraneus da Lorto, former Genoese governor of Caffa and emissary of Uzbeg Khan of the Golden Horde.
[5] It was conjectured that Angelino Dalorto moved to Majorca, possibly as a commercial agent for his family's trading house, and took up the name 'Dulcert' as a more Catalan-sounding version of his surname.
Whether this was a Latinisation of the Genoese toponym Dulcedo or that of the Catalan surname Dolcet, is a question I shall leave to those who pursue national glory.
What interests us is where he trained as a cartographer and where he engaged in his professional career as such, and the toponymy of his charts leaves no room for doubt about the Genoese provenance of his cartographic-toponymic pattern.
[10]Angelino "Dalorto" is known for a portolan chart commonly dated 1325 (now revised to 1330), privately held by the Prince Corsini collection in Florence.
For the most part, Dalorto follows the restrained coast-focused Italian style, exemplified by the early portolans of his Genoese predecessor Pietro Vesconte, but he also begins moving away from its sparseness by illustrating inland details, such as miniature cities, mountain ranges and rivers, a tendency will flourish in the later Majorcan school.
Among its advances in geographic knowledge, the Dalorto map gives a better picture of northern Europe (particularly the Baltic Sea) than its predecessors.
Its signature reads: "ano MCCCXXXVIIII mense Augusto Angelino Dulcert in civitate Maioricarum composuit".
[18] The oldest heraldic representation connected with Macedonia surviving to the present time, or discovered so far, is the banner of Skopje, on the Dulcert 1339 Map, with blazon: Or, double-headed eagle Gules.
