How to classify the palmar lines: the simian line, Sydney line & the Suwon crease!

–

The study of the palmar lines [folding creases] traces back to the ancient civilisations of the Chinese and Indians as early as 3,000 years B.C. Historically the palmar lines have been adopted as the most important ‘tool’ of the classic Indian palmist with the purpose for ‘the guidance of humanity’. This explains why in all regions of the world the palmar lines became synonymous with the stigma of fortune telling (advocated by so-called ‘predictive palmistry’) – and subsequently debarring the hand lines from the scientific courts.

However, since the end of the 19th century the hand lines have been adopted by scientific researchers for other purposes, including: anthropological classification, personal identification (though the fingerprints are more well-known for this purpose), and hand lines also have a diagnostic purpose!

The combination of the heart line (distal transverse crease) & head line (proximal transverse crease) could be described as representing the most important aspect of the palm lines. The typical characteristics of these two so-called ‘transverse creases‘ (= heart line + head line) can be described as follows (see also the picture above):

• COMMON LINES: The heart line & the head line typically manifest as 2 unconnected lines, and only in human hands these lines typically do not cross the full palm (in the primate palm there are usually mulitiple horizontal lines which cross the full palm).

• SYDNEY LINE: The Sydney line can be recognized by the presence of an extended head line which crosses the full palm, combined with the presence of a normal heart line (both lines are required not to connect/fuse with eachother). NOTICE: From a scientific point, in medical science the Sydney line has been recognized in medical science as a ‘minor physical anomaly’ (MPA), and it became also known as a typical marker for e.g. the hand in Down syndrome, the hand in fragile-X syndrome, the hand in psoriasis & the hand in Schizophrenia. The name‘Sydney line’ was introduced in 1968 by Australian researcher S.G. Purvis-Smith who reported a high prevalance of Sydney lines in patients with congenital rubella. 

• EXTENDED HEART LINE: The extended heart line can be recognized by the presence of a very long heart line which crosses the full palm, combined with the presence of a normal head line (both lines are required not to connect/fuse with eachother). NOTICE: From a scientific point of view there is not much know about the extended heart line.

• SIMIAN CREASE: The simian crease can be recognized by the presence of a fusion between the head line and the heart line – resulting in the impression that one of both lines is missing. NOTICE: From a scientific point, in medical science the simian line has been recognized as a ‘minor physical anomaly’ (MPA), and it became also known as a typical marker for e.g. many syndromes (including Down syndrome) and many diseases such as the hand diabetes mellitus & the hand in rheumatoid arthritis. The name simian line was introduced in 1877 by French physician Paul Broca who described it as an unusual characteristic for the human hand.

• SUWON CREASE: The Suwon crease can be recognized by the presence of two complete head lines (not a splitting head line, nor an interrupted head line), and the upper head line fuses/connects with the heart line. NOTICE: The history of the Suwon crease is still very young: it was first described in 2010 by Korean researchers, who found it only in 0.7% of a large Korean sample of 3.532 male hands (in the 1664 female hands it was never observed).

An advanced definition of various types of palmar creases.

 

The Korean researchers have presented in 2010 a new detailed method for classifying the various types of palmar lines, which includes some interesting elements which can be applied in Multi-Perspective Palm Reading:

 

“Definition of major and minor palm creases. Major palm creases are defined as follows. Radial longitudinal crease (I) becomes distinct according to the flexion of carpometacarpal joints of the thumb. Proximal (II) and distal transverse creases (III) become distinct according to the flexion of the metacarpophalangeal joints of the second to fifth fingers. Minor palm creases are defined as palm creases which are narrower than the two times of the epidermal groove width in palmprints (1), apart from major palm creases (2), crossing major palm creases (3), or leading to major palm creases by the sharpened end (4).”
