ANCIENT ORIGINS: The Golem: Talmudic Legend of a Clay Beast Created to Protect the Jews (Ḏḥwty). Interesting post that seems more or less accurate, but suffers from the lack of primary references. If you are going to write about ancient texts, always include specific references so people can look the passages up themselves. A very old Philologos column on the Golem legend is noted here. The link has rotted but the excerpt is informative and at least gives general references.
