JOANNA, an English fanatic, was born in Devonshire about 1750. She was employed originally as a domestic servant; but having been an adherent of the Methodists, she, at about the age of 40, set up for a prophetess. She wrote, dictated, and rhymed prophecies, and announced herself as the woman spoken of in the 12th chapter of the Revelation. She published her unintelligible jargon to the world, and, strange to say, her followers soon swelled out to the number of 100,000. When beyond the age of 60, she announced that she was to be delivered of a "Second Shiloh" on the 19th October 1814. Her fanatical dupes, in great numbers, stood watching round her door, day and night, till the 19th passed away; but "Shiloh" failed to appear, and it was announced to the multitude that the prophetess had fallen into a trance. She died of dropsy on the 27th December 1814. Her followers have now (1860) dwindled down to an almost nominal existence. She declared a short while before her death, that "if she was deceived, she was at all events misled by some spirit, either good or evil." Curious to say, her most substantial supporter was William Sharp, the eminent engraver. (See Sharp.)
