A haruspex was a specialist in interpreting divine signs within Etruscan and Roman religious traditions. Haruspices are best known for examining the internal organs of sacrificial animals, especially the liver. Their expertise also extended to lightning, unusual events and the religious response to reported prodigies.
A haruspex was not the same as an augur. Roman augurs belonged to a distinct priestly college and supervised the rules governing auspices in public affairs. Haruspices practised a different body of expertise, associated above all with Etruria. Both could advise on public religious matters, but their responsibilities were not interchangeable.
Nor was a haruspex simply the attendant who killed a sacrificial animal. Slaughter, examination of the organs and interpretation were separate activities within a sacrifice.
The examination focused on the condition and unusual features of the organs. These were interpreted as signs concerning relations between humans and gods, not as a veterinary diagnosis. An unfavourable result could call for another sacrifice or expiatory measures. In Roman public religion, restoring acceptable relations with the gods mattered as much as predicting a particular event.
Roman authors called this Etruscan body of religious learning the disciplina Etrusca. Traditions traced its origin to the revelation of Tages. Such stories express ancient beliefs about sacred knowledge; they are not a securely documented biography of a historical founder.
The bronze model of a sheep's liver found near Piacenza belongs to the late Etruscan period, usually dated to the second or first century BCE. Its surface is divided into fields bearing Etruscan divine names. It is commonly interpreted as a teaching aid connected with the reading of entrails. The object shows the systematic character of the practice, but does not allow every ancient ritual to be reconstructed with certainty.
It belongs to the collections of the Musei di Palazzo Farnese in Piacenza.
In the Republic, the Senate could consult Etruscan specialists about prodigies and the rites needed in response. Haruspicy continued under the emperors. This does not mean that all Romans accepted its claims: Cicero's dialogue On Divination presents arguments both for and against divinatory practices.
Accounts of successful predictions therefore need caution. A narrative written after an event might give that event religious significance. Inscriptions, images, ritual objects and the specialists' institutional role provide evidence alongside literary anecdotes.
