Shroud usually refers to an item, such as a cloth, that covers or protects some other object. The term is most often used in reference to burial sheets, mound shroud, grave clothes, winding-cloths or winding-sheets, such as the famous Shroud of Turin or Tachrichim (burial shrouds) that Jews are dressed in for burial. Traditionally, mound shrouds are made of white cotton, wool or linen, though any material can be used so long as it is made of natural fibre. Intermixture of two or more such fibres is forbidden, a proscription that ultimately derives from the Torah, viz., Deut. 22:11.
