First printed edition of da Foligno's treatise on bathing together with the first printing with a definite date of Castelli's work. ISTC No. ig00133000. Remarkably the ISTC cites two different separate undated printings of Bonaventura de Castello's work on the baths of Porretta both published about 1473. This dated edition also included a text by Francesco da Siena on the baths of Petrioli. These were among the earliest printings of texts concerning bathing, and very early printings on any medical subject. They probably served commercial purposes in advertising the baths as well as providing therapeutic advice.
