Golem (Jewish)
A golem is an animated, anthropomorphic being in Jewish folklore, which is entirely created from inanimate matter, usually clay or mud. The most famous golem narrative involves Judah Loew ben Bezalel, the late 16th-century rabbi of Prague. According to Moment magazine, "the golem is a highly mutable metaphor with seemingly limitless symbolism.
It can be a victim or villain, man or woman—or sometimes both. Over the centuries, it has been used to connote war, community, isolation, hope, and despair." The golem, brought into being by a human creator, becomes a helper, a companion, or a rescuer of an imperiled Jewish community. In many golem stories, the creature runs amok and the golem itself becomes a threat to its creator.
