A golem (ˈɡoʊləm ; gōlem) 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 word golem occurs once in the Bible in Psalm 139:16, which uses the word גלמי (golmi; my golem), that means "my light form", "raw" material, connoting the unfinished human being before God's eyes. The Mishnah uses the term for an uncultivated person: "Seven characteristics are in an uncultivated person, and seven in a learned one", (שבעה דברים בגולם) (Avot 5:7 in the Hebrew text; English translations vary).
In Modern Hebrew, golem is used to mean "dumb" or "helpless", or a pupa. Similarly, it is often used today as a metaphor for a mindless lunk or entity that serves a man under controlled conditions, but is hostile to him under other conditions. "Golem" passed into Yiddish as goylem to mean someone who is lethargic or beneath a stupor.
The oldest stories of golems date to early Judaism. In the Talmud (Tractate Sanhedrin 38b), Adam was initially created as a golem (גולם) when his dust was "kneaded into a shapeless husk". Like Adam, all golems are created from mud by those close to divinity, but no anthropogenic golem is fully human. Early on, the main disability of the golem was its inability to speak. Sanhedrin 65b describes Rava creating a man (gavra). He sent the man to Rav Zeira. Rav Zeira spoke to him, but he did not answer. Rav Zeira said, "You were created by the sages; return to your dust" ().
During the Middle Ages, passages from the Sefer Yetzirah (Book of Formation) were studied as a means to create and animate a golem, although little in the writings of Jewish mysticism supports this belief.
