Under Jupiter (1, [Plate VII].), they usually are brought about by blows caused generally by the subject's desire to rule and to be too dogmatic or tyrannical.
Under Saturn (2, [Plate VII].), crosses indicate injuries to the head from accidents by animals, blows by treachery, mine explosions, etc., and generally relate to accidents of a treacherous nature.
Under the Mount of the Sun (3, [Plate VII].), these crosses have been found to relate to accidents to the head from sudden falls, such as the subject striking his head by falling, concussion of the brain, etc.
Under the Mount of Mercury (4, [Plate VII].), these sharply defined crosses relate to injuries to the head due to accidents generally produced by scientific experiments or some hazardous business venture.
Small defined squares touching the Line of Head (5, [Plate VII].), are in all cases signs of preservation, and they relate to the particular qualities of the Mount of the hand under which they are found. (See chapter on Mounts, page [140].)
DOUBLE LINES OF HEAD
Double Lines of Head (6-6, [Plate VII].), are as rarely found as are cases of the single line right across the hand. In all cases where the Double Line of Head stands out distinct and clear as two separate lines, the object will be found to have a dual mentality. He is usually capable of an enormous amount of mental work and is of that class of people who carry out two separate mental lives with success. It is often found with one line joined to the Line of Life and the other rising from the Mount of Jupiter; if such is the case, the interpretation would be that one side of the nature is extremely sensitive and cautious, while the other is self-confident with a great desire to rule or enforce its mental ideas on the world.
Although such a sign as the Double Line of Head gives a remarkable degree of mentality, yet I have always found it a more successful sign to find one clear Line of Head well marked on the hand than the two Lines of Head in any of their positions.
