Note 1 — Chapter VII · Camps, Fortifications, Vitrified Forts; Santorin; The Towns upon the Hill of Hissarlik.

On this point an admirable book should be consulted, by De la Noë: “Enceintes Préhistoriques,” Mat., 1888, p. 324, in which the author says that positions protected by escarpments bordering the greater party of the circumference of the enceinte were at all times chosen for the erection of fortifications. The absence of water, however, often makes him hesitate in coming to a decision, and leads him to think that the remains where it is absent must have been temples for the worship of deities.
