numbers 17 to 19 are written as three, two and one from twenty. Similarly ciem cealψ "three from thirty" (27) etc. The numbers could be inflected for case. For example, in the Etruscan sentence "has died [at the age] of two eighty", is the genitive of zal (2) and cezpalψals is the genitive of cezpalψ (80). The 4 vs. 6 dispute There has been a longstanding controversy about the assignment of 4 and 6. All Etruscologists agree that the words are huθ (huth) and śa (sha). The disagreement is about which is which. Until recently, it was generally accepted, based on archaeological evidence, that 4 was huθ and 6 was śa. For instance, in the frescos of the Tomb of the Charons in the Monterozzi necropolis, on a hill east of Tarquinia, four Charons are represented, each one accompanied by an inscription: Next to the fourth Charon, the text reads charun huths ("the fourth Charon"). In the same necropolis, in the Tomb of the Anina, which contains six burial places, an inscription reads: sa suthi cherichunce, which has been translated as: "he built six tombs/sepulchres". However, that assignment was challenged in 2011 by a thorough analysis of 91 Etruscan gambling dice, from many different ages and locations, with numbers marked by dots ("pips"); and a lone pair of dice (the "Tuscanian dice" or "dice of Toscanella") with the numbers written out as words. Mathematically, there are 30 ways to place the numbers 1-6 on the faces of a die; or 15 if one counts together numberings that are mirror images of each other. These 15 possibilities are identified by the pairs of numbers that occur on opposite faces: (1-2, 3-4, 5-6), (1-2, 3-5, 4-6), (1-2, 3-6, 4-5), (1-3, 2-4, 5-6), (1-3, 2-5, 4-6), (1-3, 2-6, 4-5), (1-4, 2-3, 5-6), (1-4, 2-5, 3-6), (1-4, 2-6, 3-5), (1-5, 2-3, 4-6), (1-5, 2-4, 3-6), (1-5, 2-6, 3-4), (1-6, 2-3, 4-5), (1-6, 2-4, 3-5), (1-6, 2-5, 3-4) For unknown reasons, Roman dice generally used the last pattern, (1-6, 2-5, 3-4), in which every pair of opposite faces adds to 7; a tradition that continued in Europe to the present day, and has become the standard all over the world. However, among the 91 Etruscan dice from many different locations, those from 500 BCE or earlier used only the first pattern, (1-2, 3-4, 5-6), in which the opposite faces differ by 1. Those from 350
