Palm reading answer
What does a square on the sun line mean?
What this means
First confirm that the mark is a small square or rectangle touching or enclosing part of the sun or Apollo line.
In palmistry, squares often work as protective signs; on the sun line, that protection is read around public image, recognition and visible craft.
The meaning depends on what the square surrounds, whether the line continues clearly after it and whether the fate line, Mount of Apollo and both hands support the same theme.
