 In 1492 and 1493 he was a singer in Florence, and it is possible that he went to France and/or the Low Countries immediately after that.Since he is listed in Jean Crétin's poem (1497) on the death of Ockeghem along with other students of that famous composer, it has been inferred that he may have studied with Ockeghem, although if so, it is not known if this occurred before coming to Italy or during the mid-1490s.Ghiselin maintained a connection both with the French court and Ferrara, occasionally serving as an emissary.
