Pietro Vesconte (
fl. 1310–1330) was a
Genoesecartographer and
geographer. A pioneer of the field of the
portolan chart, he influenced
Italian and
Catalan mapmaking throughout the fourteenth and fifteenth centuries. He appears to have been the first professional mapmaker to sign and date his works regularly.[1]
Although Vesconte was born in Genoa, he produced much of his work in
Venice. He was active between 1310 and 1330,[1] producing numerous maps. His
nautical charts are among the earliest to map the
Mediterranean and
Black Sea regions accurately. He also produced progressively more accurate depictions of the coastlines of northern Europe, in particular that of Britain and, to a lesser extent, Ireland.
Pietro Vesconte's 1311 portolan chart of the east Mediterranean is the oldest signed and dated nautical chart that survives from the medieval period.[2] He is also the author of at least four signed multi-sheet atlases (1313, 1318a, 1318b, c. 1321), where the various sheets can be combined into a single nautical chart. There is also an atlas (1321) and a solitary portolan chart (1327) signed by "Perrino Vesconte", assumed to be either Pietro himself or possibly a younger relative member of his family using a diminutive form of 'Pietro'.[1] The image of a mapmaker at work, which appears in a Vesconte atlas of 1318, may depict the chartmaker himself.[3]
Pietro Vesconte brought his experience as a maker of portolans to bear on the
mappa mundi (circular world map) he produced, which introduced a previously unheard of accuracy to the genre.[1] He provided a world map, nautical atlas, a map of the
Holy Land and plan of Acre and
Jerusalem for inclusion in
Marino Sanuto's Liber secretorum fidelium crucis, a work which aimed to encourage a new crusade.[3] There are three known copies of Sanuto's Liber (c. 1320–21, c. 1321, c. 1325) that include Vesconte's maps, only the first of which is signed; the latter two are confidently assumed to have been done by him, or at least under his direction.
