in ancient Egyptian religion, with ka and akh, a principal aspect of the soul; the ba appears in bird form, thus expressing the mobility of the soul after death. Originally written with the sign of the jabiru bird, and thought to be an attribute of only the god-king, the ba was later represented by a man-headed hawk, often depicted hovering over the mummies of king and populace alike. Graves were frequently provided with narrow passages for visitation by the ba.
