Short answers, pulled from the story.
The House of the Tragic Poet was discovered in November 1824 by the archaeologist Antonio Bonucci. The house dates to the 2nd century BCE and was preserved by the eruption of Mount Vesuvius in 79 AD.
The House of the Tragic Poet is located in Regio VI, Insula 8, the far-western part of Pompeii. It faced the Via di Nola, one of Pompeii's largest streets, directly across from the Forum Baths of Pompeii.
Six panels from the house were relocated to the National Archaeological Museum in Naples and selected specifically for their connections to the Iliad. Those transfers inspired the alternate names Homeric House and Iliadic House.
The CAVE CANEM mosaic in the vestibule shows a domesticated dog leashed and chained, with the Latin words "CAVE CANEM" meaning Beware of the dog. The rest of the vestibule floor is decorated in a black and white checker pattern framed by two black stripes.
The house originally contained more than twenty painted and mosaic panels. Six of these have been relocated to the National Archaeological Museum in Naples, Italy.
Excavators named the house after a panel depicting a figure they interpreted as a poet reciting his work. Later scholars identified the scene as the myth of Admetus and Alcestis, and the origin of the panel itself is contested. Richardson attributed it to the Basilica at Herculaneum, while De Carolis listed it as "Casa del Poeta Tragico (?)" with a question mark.
