The register of the members of St George's cross-bow Guild of the city of Aalst (Alost) in Flanders includes three names of apothecaries: Bertelmeeux vande Putte from Ghent (1523), magister Gérard Boyengenye of Antwerp (1538) and magister Jean Jolybois (1550) of Alost itself. The last two apothecaries were until now not noticed.
