Black Doll at Old Store-shops

Is it not probable that the black doll was an image of the Virgin, sold at the Reformation with a lot of church vestments, and other "rags of Popery," as the Puritans called the surplice, and first hung up by some Puritan or Hebrew dealer. Images of the black Virgin are not uncommon in Roman Catholic churches. Has the colour an Egyptian origin, or whence is it?
