Middle Eastern parallels; anatomical model

The Piacenza liver is a striking conceptual parallel to clay models of sheep's livers known from the Ancient Near East, reinforcing the evidence of a connection (be it by migration or merely by cultural contact) between the Etruscans and the Anatolian cultural sphere. A Babylonian clay model of a sheep's liver dated to the Middle Bronze Age is preserved in the British Museum.^[2] The Piacenza liver parallels the Babylonian artifact by representing the major anatomical features of the liver (the gall bladder, caudate lobe and posterior vena cava) as sculpted protrusions.

Cosmos model; divination method

The outer rim of the Piacenza liver is divided into 16 sections; since according to the testimony of Pliny and Cicero,^{[citation needed]} the Etruscans divided the heavens into 16 astrological houses, it has been suggested that the liver is supposed to represent a model of the cosmos, and its parts should be identified as constellations or astrological signs.^{[citation needed]} Each of the 16 houses was the "dwelling place" of an individual deity. Seers would e.g. draw conclusions from the direction in which lightning was seen. Lightning in the east was auspicious, lightning in the west inauspicious (Pliny 2.143f.). Stevens (2009) surmises that Tin, the main god of lightning, had his dwelling due north, as lightning in the north-east was most lucky, lightning in the north-west most unlucky, while lightning in the southern half of the compass was not as strong an omen (Servius ad. Aen. 2.693).

Inscribed deity names

The theonyms are abbreviated and in many cases, the reading even of the abbreviation is disputed. As a result, there is a consensus for the interpretation of individual names only in a small number of cases. The reading given below is that of Morandi (1991) unless otherwise indicated:

circumference:^[3]

1. tin[ia] /cil/en
2. tin[ia]/θvf[vlθas]
3. tins/θ neθ[uns]
4. uni/mae uni/ea (Juno? Maia?)
5. tec/vm (Cel? Tellus?)
6. lvsl
7. neθ[uns] (Neptunus)
8. caθ[a] (Luna?^[4]) (This name also appears on the Lead Plaque of Magliano.)^{[citation needed]}
9. fuflu/ns (Bacchus)
10. selva (Silvanus)
11. leθns
12. tluscv
13. celsc
14. cvl alp
15. vetisl (Veiovis?)
16. cilensl

Two words are on the bottom side of the artefact:

1. tivs (or tivr "Moon" or "Month"?))
2. usils ("of the sun" or "of the day")

Gottarelli interpretation

The deciphering of the complex content of the Liver of Piacenza was the subject of two scientific monographs by the University of Bologna researcher Antonio Gottarelli (see website), published between 2017 and 2018. These books represent the most complete analysis of its content and they reveal its nature of a handheld instrument for the digital calculation of a liturgical-ritual calendar. Its dating would be at fourth century BC and the position of place of discovery at 45° of latitude would be consistent with its instrumental use.^{[citation needed]}
