“ Not only each sign, but each face, was assigned to some peculiar planet; hence whos means 'of which planet.' Besides this equal division of each sign, we find unequal divisions, called terms. For example, the sign Aries, considered as a whole, was called 'the mansion of Mars.' Again, of this sign, degrees one to ten were called 'the face of Mars'; degrees eleven to twenty, 'the face of the Sun'; and degrees twenty-one to thirty, 'the face of Venus.' Lastly, of the same sign, degrees one to six were 'a term of Jupiter' ”
