Different theories exist of the city's origin. Villanovan pottery has been found at Chiusi. One common type is a cinerary urn dating to the 8th century BC. These urns are in the shape of wattle-and-daub huts with thatched roofs, presumably the homes of the deceased. This style of architecture is so different from classical Etruscan that many Etruscologists have denied a continuity. On the other hand, it is clear that the people of the region received a strong impetus from Greek colonies such as Cumae and from Greek immigration.
