Reference excerpt

The Liver of Piacenza is an Etruscan artifact found in a field on September 26, 1877, near Gossolengo, in the province of Piacenza, Italy, now kept in the Municipal Museum of Piacenza, in the Palazzo Farnese. It is a life-sized bronze model of a sheep's liver covered in Etruscan inscriptions (TLE 719), measuring 126 × 76 × 60 mm (5 × 3 × 2.4 inches) and dated to the late 2nd century BC, i.e. a time when the Piacenza region would already have been Latin-dominated (Piacenza was founded in 218 BC as a Roman garrison town in Cisalpine Gaul).

Description and interpretation The liver is subdivided into sections for the purposes of performing haruspicy (hepatoscopy); the sections are inscribed with names of individual Etruscan deities.

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. 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, 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. In this interpretation, 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:

tin[ia] /cil/en tin[ia]/θvf[vlθas] tins/θ neθ[uns] uni/mae uni/ea (Juno? Maia?) tec/vm (Cel? Tellus?) lvsl (Usil) neθ[uns] (Neptunus) caθ[a] This name also appears on the Lead Plaque of Magliano, in the Sarcophagus of Laris Pulenas, and perhaps (as caθnis) in the Tabula Capuana (line 9). fuflu/ns (Bacchus) selva (#Silvanus) leθns tluscv celsc (Cels) cvl alp (Alpanu) vetisl (Veiovis?) cilensl interior: Two words are on the bottom side of the artefact:

tivs (or tivr "Moon" or "Month"?)[1]) usils ("of the sun" or "of the day")

Worked examples

Example 1 — a first encounter with Liver of Piacenza

Start with the simplest possible case. Write down what Liver of Piacenza claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Liver of Piacenza before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Liver of Piacenza ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Liver of Piacenza

In research: Liver of Piacenza appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Liver of Piacenza in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Liver of Piacenza is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1877 archaeological discoveries, 2nd-century BC inscriptions, 2nd-century BC sculptures, so understanding it makes those chapters shorter.
In everyday life: Look for Liver of Piacenza outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
