Simian line: what one crease across the palm means

What is a simian line?

Most palms have two horizontal creases in the upper half: the heart line under the fingers and the head line below it. On a hand with a simian line those two are replaced by one deep crease that runs from the thumb edge of the palm to the little finger edge. The life line still curves around the thumb below it, and the fate line, if there is one, still rises up the middle.

The name is old and comes from the resemblance to the creases of other primate hands. Doctors use the neutral term single transverse palmar crease, and palmists in India call it hanuman rekha. All three name the same feature.

How to tell a simian line from a close heart and head line

Many people think they have a simian line when their heart and head lines simply run close together. Check three things in good light.

1. 1.Count the creases above the life line. A true simian line leaves one, not two lines that touch.
2. 2.Follow it to both edges. A simian line reaches from the thumb side to the little finger side without a break.
3. 3.Look for a branch. If a second line splits off toward the index finger, it is a joined heart and head line, a near simian pattern.

Simian line, Sydney line and near simian patterns

Two related patterns are often mixed up with it. A Sydney line is a head line that runs all the way across to the little finger edge, while a separate heart line sits above it. It is named after Sydney, where researchers first described it. A near simian pattern, sometimes called a transitional crease, is a heart and head line joined by a strong bridge so they look like one for part of the way.

Palmists read both as milder versions of the same idea: heart and head working closely, with less of the all or nothing quality of a full simian line.

How rare is a simian line?

Unlike most palmistry marks, this one has been counted. Medical studies find a full single crease in about 1.5 to 3 percent of people in most populations, and more often in some East Asian and Native American populations. It shows on one hand more often than on both, and it is seen more often in men than in women. That makes it the rarest of the well documented palm features, and the most common answer to the question of which palm line is rare.

What does a simian line mean in palmistry?

With feeling and thinking drawn as one line, palmists read the simian line as intensity. People with it are described as wholehearted: when something matters to them they give it everything, and they find it hard to do things halfway. The same trait is read as both a strength and a challenge. Focus, determination and loyalty are the strengths. All or nothing moods, stubbornness and difficulty switching off are the challenges.

Readers also say the person may find it hard to separate what they feel from what they think, so decisions can come fast and with conviction. Popular sites add claims about genius, criminality or a special destiny. Those come from old prejudice and sensational writing and are best ignored.

Simian line on one hand or both hands

Readers follow the usual left and right logic. A simian line on the dominant hand only is read as intensity that grew with experience and shows in how you live now. One on the non-dominant hand only is read as an inborn intensity you have learned to balance, often with a separate heart and head line on the working hand to show it. A simian line on both hands is read as the trait running strongly through your whole life, with very little in between work and feeling.

Reading a hand with a simian line

With no separate heart and head lines to compare, palmists lean more on the rest of the hand. The life line is read as before, for energy and pace. The fate line, if present, shows where that intensity is aimed, and the hand shape gives the temperament it runs through. A simian line on an earth hand is read as stubborn persistence, while on a water hand it is read as deep, absorbing feeling.

Is a simian line a medical sign?

On its own, no. Most people with a single palmar crease have no medical condition at all. Doctors note it because it appears more often alongside some conditions present from birth, such as Down syndrome, so they look at it together with other features rather than alone. If you have questions about your own hand, a doctor is the right person to ask, not a palmist.
