A group of large menorah-form lamps from the Netherlands were fabricated in an unusual manner, almost completely out of sheet brass. The elements of the shaft, as well as the knobs on the arms, were made by spinning. In this technique, invented in the early nineteenth century, a wooden form with the desired shape is rotated at high speed, and the sheet metal is pressed against it with a blunt tool.
A pleasing decorative effect was created by using two different color metals, one a reddish copper and the other a yellow brass. Four other lamps of this type are known and are remarkably similar in form. Three have a cast finial consisting of a lion holding a shield with three X's on it; this is the emblem of the city of Amsterdam. One of the examples comes from a Dutch synagogue. These factors indicate an origin in the Netherlands.
