point are the parallels adduced from the Indian area, where the
association of iron tridents with ' thunderstones' is a very note-
worthy fact. But most cogent of all is the analogy of the hypaethral
trident-mark to the hypaethral bidental, and indeed the whole history
of the Athenian Erechtheion.

and more irregular, at a little distance from them. These marks—
I am disposed to conjecture—were originally a series of neolithic
' cup-marks2.' If so, they are of peculiar interest as being the oldest
traces of cult on the Athenian Akropolis. The exact significance
of 'cup-marks' is unknown3; but it is noticeable that, wherever

while k'1 is plugged at a depth of o-7om. These dimensions imply that the original ' cup-

Athenians were not above a yevvvuov \pev5os.

a prolonged radius may be highly stylised human figures, such as are met with in the
