It has been found in Mycenaean tombs; it is known from lake-dwellings in Switzerland, and it occurs with neolithic remains in Denmark, whilst in England it is found with interments of the bronze age.
This monumental work seems to date from the close of the Middle Minoan age, but has been re-used for interments at successive periods (Evans, Archaeologic, 1906, p. 136 sqq.).
In the case of poorer interments the destruction of the body was, on the contrary, often accelerated by the use of quicklime.
Marchi has estimated the united length of the galleries at from Boo to 00o m., and the number of interments at between 6,000,000 and 7,000,000; Martigny's estimate is 587 m.; and Northcote's, lower still, at " not less than 350 m."
