Witches' Sabbath 1789 by GOYA Y LUCIENTES, Francisco de

The old superstitious, heathen cult of Pan that was persecuted by the Church but which still persisted in the more remote corners of the country was the subject of Goya's attack in this painting. Among a group of fanatic and stupidly credulous women and witches sits a huge ram, demanding one of the children as sacrifice. On the ground lies the emaciated body of a child. The moon and a swarm of bats overshadow the day and darken the sky. The symbols all point to the Spanish Inquisition.
