GIACOMO da MILANO. - Franciscan writer, of the Capelli or de Capellis family, who lived during the 13th century, and was a lector at the convent of Milan.
He is the author of the noteworthy little work *Stimulus amoris* (Quaracchi 1905; Tuscan vernacular edition by A. Levasti, *I mistici del Duecento e del Trecento*, Milan 1925, pp. 239-51, 990), which was widely circulated. This work was later expanded into another compilation with the same title by an unknown author of the 14th century (edition by C. Guasti, Milan 1934). The fervent mysticism that permeates it, along with its dependence on the thought and spirit of St. Bonaventure, led to its attribution to the Seraphic Doctor.

Nothing prevents the identification of G. da M. with the friar Jacobus de Capellis, of the same convent in Milan, who authored a *Summa contra haereticos*, composed around the mid-13th century and directed against the various Cathar sects of ancient Lombardy. It is therefore likely that he also served as an inquisitor. Furthermore, the Ambrosian Library in Milan preserves a manuscript (42 sup.) containing 52 *Conciones quadragesimales* by the friar Fabiolo Capelli; an examination of this unpublished work could shed further light on the figure and literary activity of this interesting author.
