Avowavofievov^ : it then increases and becomes full at mid- 
niglit, after wliich it again visibly decreases. In lUyricmn 
there is a cold spring, over wliich if garments are spread 
they take fire. The pool of Jupiter Ammon, which is cold 
during the day, is warm during the night ^. In the country 
of the Troglodytse^, what they call the Fountain of the Sun, 
about noon is fresh and very cold ; it then gradually grows 
w^arm, and, at midnight, becomes hot and saline"^. 
In the middle of the day, during summer, the source of 
the Po, as if reposing itself, is always dry^. In the island 
of Tenedos there is a spring, which, after the summer sol- 
stice, is full of water, from the third hour of the night to 
the sixth ^. The fountain Inopus, in the island of Delos, 
decreases and increases in the same manner as the Nile, 
and also at the same periods'^. There is a small island in 
the sea, opposite to the river Timavus, containing warm

loquitur, insititia quiete." Hardouin in Lemaire, i. 443. He says that 
there is a similar kind of fountain in Provence, called CoUis Martiensis. 
2 There has heen considerable difference of opinion among the com- 
mentators, both as to the reading of the text and its interpretation, for 
which I shall refer to the notes of Poinsmet, i. 307, of Hardouin and 
Alexandre, Lemaire, i. 443, and of Richelet, Ajasson, ii. 402. 
^ We have an account of the Troglodytse in a subsequent part of the 
work, V. 5. The name is generally apphed by the ancients to a tribe of 
people inhabiting a portion of ^Ethiopia, and is derived from the circum- 
stance of their dweUings being composed of caverns ; a rpojyX/) and duvcj. 
Alexandre remarks, that the name was occasionahy apphed to other tribes, 
whose habitations were of the same kind ; Lemaire, i. 443. They are re- 
ferred to by Q. Curtius as a tribe of the ^Ethiopians, situated to the south 
of Egypt and extending to the E;ed Sea, iv. 7. 
^ Q.. Curtius gives nearly the same account of this fountain. 
5 The Po derives its water from the torrents of the Alps, and is there- 
fore much affected by the melting of the snow or the great falls of rain, 
which occur at different seasons of the year ; but the daily diminution of 
the water, as stated by our author, is without foundation.

de la Troade, t. i. p. 219." Lemafre, i. 444. 
7 Strabo, in aUusion to this cfrcumstance, remarks, that some persons 
make it stUl more wonderful, by supposing that this spring is connected 
with the Nile. We learn from Tournefort, that there is a well of this 
i).ame in Delos, which he found to contain considerably more water in 
January and February than in October, and which is supposed to be con- 
nected with the NUe or the J ordan : this, of course, he regards as an idio 
tale. Lemaire.
