Stanhope, John Spencer: Olympia or topography illustrative of the actual state of the plain of Olympia and of the ruins of the city of Elis (London, 1824)

Ti-IK HIPPODROME.

Having thus given to my renders, in M. Fauvel's own words, the
impression produced on his mind by the appearance of this spot, I will
endeavour to explain to them the theory grounded upon this description,
by the Count de Clioiseul. His first object was, to show that the newly
discovered Hippodrome coincided in dimensions with the Hippodrome
of Olympia: it was therefore necessary to begin by ascertaining these
dimensions. He justly concluded that the Hippodrome was at least two
stadia in length, as the dromos, or simple course, which consisted in one turn
up and down the Hippodrome, was of four stadia; to this was to be added
a space at each extremity, sufficient to admit of the passage of the chariots
round the posts. The two stadia make 189 toises. He finds 230 on his
[dan, which leaves 40 to be divided at the two extremities. He appears, in
this instance, to differ from M. Fauvei, who found only 200 toises in the
length of the Hippodrome. The width he stated to coincide with sufficient
accuracy with that of 400 Greek feet, assigned to the Hippodrome by M.
Barbie du Bocage, and computed by him, according to d'Anville, at 63 or
64 toises.
