In Scotland a certain number of identifications are also possible. Alison Peirson, tried in 1588, learnt all her charms and obtained all her knowledge from the Devil, who came to her in the form of Mr. William Sympson, her mother's brother's son, who was a great scholar and doctor of medicine in Edinburgh.[136] Jonet Stewart in 1597 'learnt her charms from umquhill Michaell Clark, smyth in Laswaid, and fra ane Italean strangear callit Mr. John Damiet, ane notorious knawin Enchanter and Sorcerer'.[137] In the trial of Marion Pardon of Hillswick in 1644 'it was given in evidence that a man spoke of the devil as Marion Pardon's pobe, i.e. nurse's husband or foster father'.[138] In a case tried at Lauder in 1649 there is an indication that one of the magistrates was the Chief of the witches; Robert Grieve accused a certain woman at a secret session of the court, 'but the Devil came that same night unto her, and told her that Hob Grieve had fyled her for a witch'.[139] Isobel Ramsay in 1661 was accused that 'you had ane uther meiting wt the devill in yor awne hous in the liknes of yor awne husband as you wes lying in yor bed at qch tyme you engadged to be his servant and receaved a dollar from him'.[140] When a man had special knowledge as to which women were witches, it is suggestive that he might be himself the Devil; as in the case of the Rev. Allan Logan, who 'was particularly knowing in the detection of witches. At the administration of the communion, he would cast his eye along, and say: "You witch wife, get up from the table of the Lord", when some poor creature would rise and depart.'[141] It seems probable that the infamous Abbé Guibourg was the head of the Paris witches, for it was he who celebrated the 'black mass' and performed the sacrifice of a child, both of which were the duties of the 'Devil'.[142]
