A kleroterion (Ancient Greek: κληρωτήριον) was a randomization device used by the Athenian polis during the period of democracy to select citizens to the boule, to most state offices, to the nomothetai, and to court juries.

The kleroterion was a slab of stone incised with rows of slots and with an attached tube. Citizens' tokens—pinakia—were placed randomly in the slots so that every member of each of the tribes of Athens had their tokens placed in the same column. There was a pipe attached to the stone which could then be fed dice that were coloured differently (assumed to be black and white) and could be released individually by a mechanism that has not survived to posterity (but is speculated to be by two nails; one used to block the open end and another to separate the next die to fall from the rest of the dice above it[1]). When a die was released, a complete row of tokens (so, one citizen from each of the tribes of Athens) was either selected if the die was coloured one colour, or discarded if it was the alternate colour. This process continued until the requisite number of citizens was selected.


Prior to 403 BCE, courts published a schedule and number dikastes required for the day. Those citizens who wanted to be dikasts queued at the entrance of the court at the beginning of the court day. Originally, the procedure was based on "first come, first serve." Beginning in 403 BCE, Athenian allotment underwent a series of reforms, and from 370 BCE onwards, they employed the kleroterion.[2]


In Aristotle's Constitution of the Athenians, Aristotle gives an account of the selection of jurors to the dikastra. Each deme divided their dikastes into ten sections, which split the use of two kleroteria. Candidate citizens would place their identification ticket -pinaka- in the section's chest. Once each citizen who wished to become judge for the day placed their pinka in the chest, the presiding archon would shake the chest and draw out tickets. The citizen whose ticket was first drawn became the ticket-inserter (empektes). The ticket-inserter would then pull out tickets and insert the tickets into their corresponding section.The Kleroterion was divided into 5 columns, one column per tribe section (between 2 machines). Each row was known as a kanomides. Once the ticket-inserter filled the kleroterion, the archon then placed a mix of black and white dice (Kyboi) into the side of the kleroterion. The number of white dice was proportional to the number of jurors needed. Then, the archon would allow the dice to fall through a tube on the side of the kleroterion and draw them one by one. If the die was white, the top row would be selected as jurors. If the die was black, the archon would move on to the next row down from the top and repeat until all the juror positions were filled for the day.[3][4]


The first significant examination of Athenian allotment procedures was James Wycliffe Headlam's Election by Lot, first published in 1891. Aristotle's Constitution of the Athenians, the text of which was first discovered in 1879 and first published as Aristotle's in 1890, became an important resource for scholars. Throughout the text, Aristotle makes references to a lottery system which was used to appoint government officials. Archaeologists first discovered kleroteria in the 1930s in the Athenian Agora, which were dated to the second century BC. Sterling Dow's Aristotle, the Kleroteria, and the Courts (1939) gave an overview and analysis of the discovered machines. Prior to Sterling Dow's 1939, the word kleroterion in Aristotle was often translated as "allotment room." However, Dow reasoned that kleroterion cannot be translated to mean "room," as Aristotle writes that "There are five kanomides in each of the kleroteria. Whenever he puts in the kyboi, the archon draws lots for the tribe the kleroterion."[5][6] Dow also concluded that Aristotle's 4th century description of the kleroterion applied to the 2nd century kleroterion.
In 1937, Sterling Dow published a catalog of his archaeological discoveries in the Athenian Agora.[7] In it, he describes 11 kleroteria fragments:

Sterling Dow's Kleroterion Fragments[7]
Fragment Description
I Most complete fragment, contains only one column of slots. Intact groove and inverted cone to place dice into
II 2 columns of slots, 7 intact in one column and 8 in the other. Significant overhang above
III Traces indicate 4 columns, much larger cone
IV Small fragment
V Small fragment but significant because the grooves for slots were unusually long and angled.
VI Multiple small fragments, presumed to be parts of much larger machine
VII Small fragment
VIII Small fragment, but can infer that it was part of a large kleroterion with nearly 300 slots
IX Uneven holes and poor workmanship
X Large and well preserved fragment, inferred to be about half of the original
XI Largest section of the kleroteria, possibly with nearly 1000 slots
