Ursula Southeil (c. 1488 – 1561; also variously spelt as Ursula Southill, Ursula Soothtell or Ursula Sontheil), popularly known as Mother Shipton, is said to have been an English soothsayer and prophetess. She has sometimes been described as a witch and is associated with folklore involving the origin of the Rollright Stones of Oxfordshire, reportedly a king and his men transformed to stone after failing her test. William Camden reported an account of this in a rhyming version in 1610.
