COHEN , Italian family of majolica makers, active in Pesaro and Ancona from 1614 to 1673. The following names are known: isaac (Pesaro, 1613–14), jacob (Ancona, 1654), and isaac (ii; Ancona, 1673–77). Together with the *Azulai family, the Cohen family produced most of the majolica seder dishes that were made in Renaissance Italy. In the case of dishes made by Jacob Cohen, the manufacturer's mark is a crown to denote priesthood, instead of the usual Star of David.
