I have a Simian Left-Hand
Most people have two major transverse lines in the upper half of the palm. In Palmistry and Hand Analysis these are called the Heart Line and the Head Line.
When the Heart Line and Head Line are fused together, only one major line is present, and it extends all the way across the hand from edge to edge. This is called a "Simian Line", or "Simian Crease". Medical references call it the "proximal transverse palmar crease" or "single palmar crease".
(But I still have a head-line at least)
This hand does not mean there are two simian lines possible. It just indicates that a high simian line (A) or a low simian line (B) is possible. It is quite difficult to discern which type one has if the line is somewhere in between the high and low positions. In any case, the higher the simian line is on the palm, the more emotional energy is affecting all activities. The lower the simian line is on the palm, the more logic and mental powers affect all activities.
The name "simian" was adopted many years ago and comes from the fact that some monkeys have only one crease in their palm.
Approximately 4% of Caucasians have this line on at least one hand. Approximately 13% of all Asians have it on at least one hand. It is even rarer to have this line on both hands.
A computer search of the medical literature reveals numerous attempts to link dermatoglyphics (skin markings) to medical disorders. At least fourteen chromosomal abnormalities are listed in the medical literature that have a high correlation (up to 84%) with the occurrence of a Simian Line. Down Syndrome is one of these diseases due to a chromosome abnormality. Does that mean that every person with a Simian Line is likely to have something medically wrong with them? No! There are many people with Simian Lines that do not have more than the average medical problems.
[NOTE: An informal and unscientific on-going survey on this web site for people with one or more simian lines indicates that the majority of the surveyors do not have more than the normal physical problems. You can see the results for all questions in graphic form here.]
Palm readers and Hand Analysts have observed over the years some common traits in people with Simian Lines on one or both hands. [This pertains to those people who have no apparent medical problems.] People with Simian Lines generally live their life differently than most other people who do not have Simian Lines. Not necessarily living better nor worse. Just living more intensely with an undercurrent of uneasiness. It is interesting that a number of well known people with a Simian Line have made a positive contribution to history. They include British Prime Minister Tony Blair (both hands), former Russian President Nikita Kruchev, writers John Steinbeck and Henry Miller, to name some well documented cases.
In personally talking with people who have one or more simian lines I have confirmed some common traits that they seem to share. I also did hypnosis with two individuals with simian lines and discovered an interesting connection to past lives concerning their simian lines. This is an ongoing project with me since 1985 and I have documented some of my more interesting findings in the second edition of my book, "Secrets of Hand Analysis".
