A mosaic floor in the home of a man named Aulus Umbricius Scaurus depicts jars of garum ready for sale (Scaurus owned a store that sold garum). Because garum was made from all kinds of fish (including shellfish and fish without scales), kosher law prevented Jews from consuming most garum. Evidence of kosher garum (called garum castum or garum muria) suggests that there were enough Jews living in Pompeii to create a market for the special variety of kosher garum.
