 This is probably the same Giacomo as was responsible for providing lodging for Pope Innocent IV at Stella in 1244 and appears in an act of 7 March 1247 in the "Liber Jurium Januae".He was also elected one of the fifteen "reggitori della città" (rectors of the city) in 1262 after the overthrow of Guglielmo Boccanegra.Luca Grimaldi, another troubadour, was one of the others.
