The most famous golem narrative involves Judah Loew ben Bezalel, the late 16th century rabbi of Prague, also known as the Maharal, who reportedly "created a golem out of clay from the banks of the Vltava River and brought it to life through rituals and Hebrew incantations to defend the Prague ghetto from anti-Semitic attacks" and pogroms. Depending on the version of the legend, the Jews in Prague were to be either expelled or killed under the rule of Rudolf II, the Holy Roman Emperor. The Golem was called Josef and was known as Yossele. It was said that he could make himself invisible and summon spirits from the dead. Rabbi Loew deactivated the Golem on Friday evenings by removing the shem before the Sabbath (Saturday) began, so as to let it rest on Sabbath.[6] One Friday evening Rabbi Loew forgot to remove the shem, and feared that the Golem would desecrate the Sabbath. A different story tells of a golem that fell in love, and when rejected, became the violent monster seen in most accounts. Some versions have the golem eventually going on a murderous rampage.
The rabbi then managed to pull the shem from his mouth and immobilize him in front of the synagogue, whereupon the golem fell in pieces. The Golem's body was stored in the attic genizah of the Old New Synagogue, where it would be restored to life again if needed. According to legend, the body of Rabbi Loew's Golem still lies in the synagogue's attic. When the attic was renovated in 1883, no evidence of the Golem was found.
