of the head or brain or middle natural line of the triangle.

That line, however, which begins from the line of life, crossing through the palm and receding toward the percussion of the hand and the mount, we call the line of the head or brain, or the middle natural [line], and the left [side] of the triangle. We call that the table [line]

which, beginning under the mount of the little finger, proceeds through the palm of the hand and stretches toward the mount of the index finger, or of Jupiter. Sometimes, however, it ascends the mount itself; sometimes it is joined with the line of the head; sometimes it falls between the index and middle fingers; and sometimes it is extended into two, sometimes three, branches, and each branch holds diverse meanings; and sometimes it stretches in the form of a branch or palm toward the mount of Jupiter. There is another line which recedes from the restriction or the joint

of the hand, meeting the palm and the fingers, called the line of prosperity or of Saturn. This supports the other lines that might lack their own power. And sometimes a branch rises from this line, which extends almost across the hand and is joined with the middle natural [line]. This is the reason why a triangle is formed in the hand. This line further sometimes does not appear in the hand and is called the base of the triangle; sometimes it extends only as far as the middle [line]
base of the triangle.

and does not progress further; sometimes it proceeds as far as the mount of Saturn, near the joint of the middle finger; and sometimes it is joined to the line of life, in the middle of which it is sometimes seen with two, sometimes with three branches tending toward the middle natural [line]; and sometimes it is dispersed in the concavity of the hand. And when these lines meet in proportion
