ca. 1503 C.E.

Employment of Christian Servants Prohibited to Jews [Germany] [Provisional]: “It is not allowed for Jews to employ Christians in their houses on a permanent basis, as it has been banned by the popes. It is however allowed that Jews hire Christians as day laborers as long as they don’t spend the night in the house and take their meals separately.”
