About Invention

A tally (or tally stick) was an ancient memory aid device used to record and document numbers, quantities, or even messages. Tally sticks first appear as animal bones carved with notches, in the Upper Paleolithic, a notable example is the Ishango Bone. Historical reference is made by Pliny the Elder (AD 23–79) about the best wood to use for tallies, and by Marco Polo (1254–1324) who mentions the use of the tally in China. Tallies have been used for numerous purposes such as messaging and scheduling, and especially in financial and legal transactions, to the point of being currency.

Principally there are two different kinds of tally sticks, the single and the split tally. A common form of the same kind of primitive counting device is seen in various kinds of prayer beads.


The single tally stick was an elongated piece of bone, ivory, wood, or stone which is marked with a system of notches. The single tally stick serves predominantly mnemonic purposes. Related to the single tally concept are messenger sticks (e.g., Inuit tribes), the knotted cords, khipus or quipus, as used by the Inca. Herodotus (c. 485–425 BC) reported the use of a knotted cord by Darius I of Persia (c. 521–486 BC).


The split tally was a technique which became common in medieval Europe, which was constantly short of money (coins) and predominantly illiterate, in order to record bilateral exchange and debts. A stick (squared hazelwood sticks were most common) was marked with a system of notches and then split lengthwise. This way the two halves both record the same notches and each party to the transaction received one half of the marked stick as proof. Later this technique was refined in various ways and became virtually tamper proof. One of the refinements was to make the two halves of the stick of different lengths. The longer part was called stock and was given to the party which had advanced money (or other items) to the receiver. The shorter portion of the stick was called foil and was given to the party which had received the funds or goods. Using this technique each of the parties had an identifiable record of the transaction. The natural irregularities in the surfaces of the tallies where they were split would mean that only the original two halves would fit back together perfectly, and so would verify that they were matching halves of the same transaction. If one party tried to unilaterally change the value of his half of the tally stick by adding more notches, those notches would not be on the other tally stick and would be revealed as an attempted forgery. The split tally was accepted as legal proof in medieval courts and the Napoleonic Code (1804) . Along the Danube and in Switzerland the tally was still used in the 20th century in rural economies.
