PEGOLOTTI, FRANCESCO BALDUCCI (fl. Florentine merchant and writer, was a factor in the service of the mercantile house of the Bardi, and in this capacity he was at Antwerp from 1315 (or earlier) to 1317; in London in 1317 and apparently for some time after; in Cyprus from 1324 to 1327, and also in 1335, when he obtained from the king of Little Armenia (i.e., mediaeval Cilicia, etc.) a grant of privileges for Florentine trade. Between 1335 and 1343, he compiled his Libro di divisamenti di paesi e di misuri di mercatanzie e d'altre rose bisognevoli di sapere a' mercatanti, commonly known as the Pratica della mercatura (the name given it by Pagnini). Beginning with a sort of glossary of foreign terms then in use for all kinds of taxes or payments on merchandise as well as for "every kind of place where goods might be bought or sold in cities," the Pratica next describes some of the chief trade routes of the 14th century, and many of the principal markets then known to Italian merchants; the imports and exports of important commercial regions; the business customs prevalent in those regions; and the comparative value of the leading moneys, weights and measures.
