Margaret Alice Murray,
Child-Sacrifice among European Witches
“ It is possible that the killing of children by poison was one method of sacrifice when the cult was decadent and victims difficult to obtain. Both Reginald Scot, writing in 1584, and Sinistrari d’Ameno in the following century, state that “this must be an infallible rule that everie fortnight, or at the least everie month, each witch must kill one child at the least for hir part.” ”
