It is also clear that Marguerite Montvoisin[227] in Paris had been instructed in witchcraft from an early age; but as the trial in which she figures was for the attempted poisoning of the king and not for witchcraft, no ceremonies of initiation or admission are recorded.

In Great Britain the ceremonies for the reception of children are not given in any detail, though it was generally acknowledged that the witches dedicated their children to the Devil as soon as born; and from the evidence it appears that in many cases the witches had belonged to that religion all their lives. It was sometimes sufficient evidence against a woman that her mother had been a witch,[228] as it presupposed that she had been brought up as a worshipper of the Devil.

The Anderson children in Renfrewshire were all admitted to the society at an early age.[229] Elizabeth Anderson was only seven when she was first asked to swear fealty to the 'black grim Man.' James Lindsay was under fourteen, and his little brother Thomas was still 'below pupillarity' at the time of the trial, where he declared that he had been bribed, by the promise of a red coat, to serve 'the Gentleman, whom he knew thereafter to be the Devil'.[230] At Forfar in 1661, Jonet Howat was so young that when Isabel Syrie 'presented hir to the divell, the divell said, What shall I do with such a little bairn as she?' He accepted her, however, and she was evidently the pet of the community, the Devil calling her 'his bonny bird'.[231] At Paisley, Annabil Stuart was fourteen when, at her mother's persuasion, she took the vows of fidelity to the Devil.[232]

Elizabeth Frances at Chelmsford (tried in 1556) was about twelve years old when her grandmother first taught her the art of witchcraft.[233] Elizabeth Demdike, the famous Lancashire witch, 'brought vp her owne Children, instructed her Graund-children, and tooke great care and paines to bring them to be Witches'.[234] One of her granddaughters, Jennet Device, was aged nine at the time of the trial.

In Sweden the children were taken regularly to the assemblies,[235] and in America[236] also a child-witch is recorded in the person of Sarah Carrier, aged eight, who had made her vows two years before at her mother's instigation.

The ceremony for the admission of adults who were converts to the witch religion from Christianity follow certain main lines. These are (1) the free consent of the candidate, (2) the explicit denial and rejection of a previous religion, (3) the absolute and entire dedication of body and soul to the service and commands of the new Master and God.

The ceremonies being more startling and dramatic for adults than for children, they are recorded in Great Britain with the same careful detail as in France, and it is possible to trace the local variations; although in England, as is usual, the ceremonies had lost their significance to a far greater extent than in Scotland, and are described more shortly, probably because they were more curtailed.

The legal aspect of the admission ceremonies is well expressed by Sir George Mackenzie, writing in 1699 on the Scotch laws relating to witchcraft in the seventeenth century:

'As to the relevancy of this Crime, the first Article useth to be paction to serve the Devil, which is certainly relevant, per se, without any addition.... Paction with the Devil is divided by Lawyers, in expressum, & tacitum, an express and tacit Paction. Express Paction is performed either by a formal Promise given to the Devil then present, or by presenting a Supplication to him, or by giving the promise to a Proxie or Commissioner impowered by the Devil for that effect, which is used by some who dare not see himself. The Formula set down by Delrio, is, I deny God Creator of Heaven and Earth, and I adhere to thee, and believe in thee. But by the Journal Books it appears, that the ordinary Form of express Paction confest by our Witness, is a simple Promise to serve him. Tacit Paction is either when a person who hath made no express Paction, useth the Words or Signs which Sorcerers use, knowing them to be such.... Renouncing of Baptism is by Delrio made an effect of Paction, yet with us it is relevant, per se ... and the Solemnity confest by our Witches, is the putting one hand to the crown of the Head, and another to the sole of the Foot, renouncing their Baptism in that posture. Delrio tells us, that the Devil useth to Baptize them of new, and to wipe off their Brow the old Baptism: And our Witches confess always the giving them new Names.... The Devil's Mark useth to be a great Article with us, but it is not per se found relevant, except it be confest by them, that they got that Mark with their own consent; quo casu, it is equivalent to a Paction. This Mark is given them, as is alledg'd, by a Nip in any part of the body, and it is blew.'[237]

Reginald Scot,[238] writing considerably earlier, gives a somewhat similar account of the English witches, though couched in less legal phraseology:
