HANDPRINTS MAY RECORD TALLIES OR COUNTS - CONTINUED:

Handprints are a common image in rock art from time immemorial. One interesting phenomenon in handprints in European Palaeolithic cave art is the image of a handprint with one or more fingers only partially represented, or missing altogether. Whereas this used to be interpreted as missing fingers due to Ice Age frostbite, or cultural practice such as chopping off a finger as a mourning ritual, recent authors have suggested that this represents counting systems or tallies.

It is relatively easy to see how handprints with one to five fingers fully extended or folded/missing could be intended as a count of one to five (https://rockartblog.blogspot.com, May 6, 2017). But what about handprints with one or more fingers only partially represented? We have five fingers on each hand so for counting with a base ten (a decimal system) our hands are ideal, but what about other systems of enumeration such as counting to a base twelve? Many human cultures have used base twelve numeration (duodecimal) systems throughout history. Their influences have given us dozen count quantities, 12 and 24 hour clocks, 12 inches in a foot, 12 signs in the zodiac and 12 months in a year. (Wikipedia)

Hand-counting in a duodecimal system is facilitated by the fact that the four fingers have three finger bones each (phalanges) and these can be counted with the thumb of each hand. With this system you can designate a quantity of twelve on each hand, or up to twenty-four total with both hands. This leads to the proposition that the paleolithic handprints with missing portions of fingers represent numbers in a duodecimal (base twelve) counting system.

In his fascinating book Numbers and the Making of Us: Counting and the Course of Human Cultures, Caleb Everett (2017) explains this, and more in detail, how counting led to civilization and vice versa. So, is this the explanation for the handprints with missing fingers? I do not know but it is possible, what do you think?

INCOMPLETE HAND PRINTS MAY RECORD TALLIES OR COUNTS:

For quite some time there has been discussion on the question of handprints in Palaeolithic cave art with missing digits. Originally proposed as evidence of Ice Age artists losing digits to frostbite or accidents, or alternatively digits that were cut off as sacrifices in a ceremonial context, they have been more recently been proposed as evidence of tallies, or numerical records.

"Perhaps the most mysterious aspect of Palaeolithic hand stencils is that on many examples one or more fingers are missing. Early theories saw this as reflecting fingers that really were missing from their subject’s hands, either through frostbite, accidents during flintkapping, or through ritual mutilation. The former have been rejected: these societies were certainly tailoring sophisticated clothing in order to survive the harsh Ice Age climate and mittens would not be beyond their technological ken, and no flintkapper, however unskilled, would sever an entire finger. Deliberate mutilation, perhaps as part of the rituals that accompanied a rite of passage or as punishment, remains a possibility. In many cases, however, two, three or four fingers are missing from stencils, and the deliberate removal of this number – which would render the hand useless – would be suicidal to small-scale hunter societies in such hostile environments. It seems far more probable that such stencils with attenuated fingers resulted from the deliberate bending back of fingers, which have been created experimentally. In some cases too, little fingers seem to have been deliberately painted over, adding strength to this observation. In such cases unskilled work results in the blurring of finger outlines, although most Palaeolithic examples are sharp, suggesting perhaps a degree of artistic familiarity and resulting skill."

It is relatively easy to see how hand prints with one to five fingers fully extended or folded/missing could be intended as a count of one to five. Examples of this are found in the Paleolithic cave art of Europe (as seen in the examples illustrated). But, what about hand prints that illustrate partial fingers, say three and a half fingers plus the thumb. If we say that the fingers portray a count or tally, does the half finger portray a fraction? While I cannot know for certain, I must confess that I do not feel wholly comfortable stating that the Paleolithic artist/mathematician is portraying a fraction. If I am to take this proposition seriously I need another explanation for the partial finger. Luckily there is another possibility that answers this question without the need to propose fractions - a duodecimal counting system (base 12). I will write about this possibility next week.
