Potter's field
A potter's field, paupers' grave or common grave is a place for the burial of unknown, unclaimed or poverty-stricken people. The term "potter's field" is of Biblical origin, and refers to Akeldama (meaning field of blood in Aramaic), which was stated to have been purchased after Judas Iscariot's suicide by the chief priests of Jerusalem with the coins that had been paid to Judas for his identification of Jesus.
