The letters of Margherita Datini to her husband, “the merchant of Prato,” are virtually impossible to put down. Margherita is never obsequious, and never holds her tongue as she chastises Francesco for staying up too late, asks about a case before the Eight of Florence, beseeches him to help friends in prison, worries over financial transactions, and updates him on his business, the harvests, and his illegitimate child (whom she cares for) when he is away. Rich in emotional life and historical particulars, the letters are a unique window into late medieval Tuscany and women’s “work.” Thanks to Carolyn James and Antonio Pagliaro for their illuminating introduction and equally luminous translation. —Jane TylusProfessor of Italian Studies and vice provost for academic affairs, New York University
