Limbo (Lat. linibus, border or edge), according to some of the scholastic theologians, one of the places into which departed spirits are received. St. Thomas Aquinas places hell in the centre of the earth; it is encircled first by purgatory, above which extend successively the limbus infantum and the limbus patrum. The former includes children dying before baptism, who according to different dogmatists pass thence to heaven or remain for damnation. The latter, which is also called the bosom of Abraham (sinus Abrahce), includes the holy men of the old covenant, the patriarchs, and other pious ancients who died before the birth of Christ. According to the usual account, Christ opened this limbo when he went down into hell, liberated the souls detained there, and admitted them to the privileges of the blessed; and it has remained from that time closed and unoccupied. Dante describes the limbo in which he met with the distinguished spirits of pagan antiquity as the outermost circle of hell.
