Next come the various kinds of inhumation graves, the most important of which are rock-hewn chambers, many of which contain well-preserved paintings of various periods; some show close kinship to archaic Greek art, while others are more recent, and one, the Grotta del Tifone (so called from the typhons, or winged genii of death, represented) in which Latin as well as Etruscan inscriptions appear, belongs perhaps to the middle of the 4th century B.C. Fine sarcophagi from these tombs, some showing traces of painting, are preserved in the municipal museum, and also numerous fine Greek vases, bronzes and other objects.
- Both inhumation and cremation were practised in heathen times.
Inhumation graves are sometimes richly furnished.
Throughout the stone age inhumation appears to have been universal, many of the neolithic tombs being chambers of considerable size and constructed with massive blocks of stone.
In Scandinavian lands the change noted by Icelandic writers may be dated about the 5th and 6th centuries, though inhumation was certainly not altogether unknown before that time.
