I Bagni di Santa Margherita a Montici. Documenti inediti e osservazioni su un disegno di Leon Battista Alberti

The first part of the article, by Emanuela Ferretti, presents un- published documents relating to the rebuilding of the thermal baths at Santa Margherita a Montici (1449-1451), with a transcription of manuscripts revised by Gabriella Battista. This material, housed in the Florence Cathedral Archives (Archivio dell’Opera di Santa Maria del Fiore), reveals the names of the protagonists, the various phases of the building project and the type of work carried out. These sources also make it possible to identify the different roles of the professional individuals involved in the building, their names and the identity of the provveditore (administrative supervisor) of the structure, a central figure in Florentine construction practice during the Renaissance. The second part of the article, by Marco Di Salvo, reexamines the celebrated drawing of a thermal bath now unanimously accepted as by Leon Batti- sta Alberti. The measurements of this drawing are studied with the aim of establishing a more accurate sense of the building, investigating and reflecting on its scale.
