«E io sono in quel numero, benché disutile sia»: l’amicizia tra Lapo Mazzei e Francesco Datini

Abstract

The notary Lapo Mazzei (1350-1412) was a correspondent of the merchant of Prato Francesco di Marco Datini (1335 about-1410). Mazzei’s letters written to Datini from 1390 to 1410 and published by Cesare Guasti (1822-1889) are an important source because they return a significant cross-section of life and personal relations of a merchant and a notary lived in Tuscany at the end of the fourteenth century. The aim of this paper is to analyze the friendship between Mazzei and Datini and other important figures through the study of notary’s letters
