Most of the vases and fragments here published are from North Central Crete—Episkopi and Arkhanes in the province of Pedhiadha, Fortezza and Kephala near Knossos, various parts of the Palace and Little Palace at Knossos; a few pieces are added from Eleutherna, further west.
The Fortezza vases were found by Mr. Payne in 1927 in an almost completely destroyed chamber tomb of the type described in B.S.A. xxix. p. 226, Fig. 2, in the side of the hill about a mile from Knossos. They are of the protogeometric, geometric, and orientalising periods.
The type is found in some numbers at Knossos, Fortezza, Anopolis and Episkopi; there is an example in Candia Museum from Kavousi, the only specimen from Eastern Crete; the shape does not occur anywhere in the protogeometric period. In these pithoi from Fortezza, the clay varies from light yellow to buff and brown, the varnish is black, the decoration is arranged in panels; the lower part of the body is decorated with broad and narrow bands; there is a small ring foot.
