THREE:"And then the disaster followed suddenly. At about five o'clock a tremendous explosion shook the fort to the foundations; the powder-magazine had caught fire. It is impossible to describe the appalling results of that explosion; the entire middle-part of the fort collapsed in a stupendous cloud of flames, smoke and dust; it was an awful destruction, an immense avalanche of masses of concrete, fragments of armour, which in their fall crushed to death nearly the whole of the garrison. From this fantastical, confused mass, overwhelming clouds of suffocating smoke escaped through some crevices and holes.That Aenesidmus held this view is stated as a fact by Sextus, whose testimony is here corroborated by Tertullian, or rather by Tertullians informant, Soranus. We find, however, that Zeller, who formerly accepted the statement in question as true, has latterly seen reason to reject it.188 Aenesidmus cannot, he thinks, have been guilty of so great an inconsistency as to base his Scepticism on the dogmatic physics of Heracleitus. And he explains the agreement of the ancient authorities by supposing that the original work of Aenesidmus contained a critical account of the Heracleitean theory, that this was misinterpreted into an expression of his adhesion to it by Soranus, and that the blunder was adopted at second-hand by both Sextus and Tertullian.299
