Note 112 — Chapter I · THE CONTRIBUTION OF THE ANCIENT WORLD
Reading edition
Strabo, loc. cit., quotes Posidonius as stating that the ebb and flood are greatly increased at the time of the summer solstice, which, of course, is not so. Priscian, op. cit., quaest. vi, gives a truer statement, that the greatest tides are those at the equinoxes (citations from Duhem, Système, vol. ii, p. 282).
