[paragraph continues] ETH the heart; and the heart, according to the Egyptians, is the shrine of the soul; so that in its composition the name signifies 'soul enshrined in heart.' Whence also the hawk, from its correspondence with the soul, never drinks water, but blood, by which, also, the soul is sustained.
