A more elaborate ceremony, known as the grand washing (rehizah gedolah), is available for the corpses of the more significant individuals; Hillel the Elder is traditionally credited with its invention. According to this latter form of ceremony, the water used for washing was perfumed by rose, myrtle, or aromatic spices; the use of spices was an ancient practice,[23] and the Mishnah especially mentions the washing ceremonies using myrtle.[24]
