Tregetour.
A conjurer or juggler. (From Old French, tresgiat = a juggling trick.) The performance of a conjurer was anciently termed his “minstrelsy;” thus we read of Janio the juggler—“Janio le tregettor, facienti ministralsiam suam coram rege … 20s.” (Lib. Comput. Garderobœ, an. (4 Edw. II. fol. 86), MS. Cott. Nero, chap. viii.)
