Et Persae aggerum altitudine iam in sublime porrecta, machinaeque ingentis horrore perculsi, quam minores quoque sequebantur, omnes exurere vi maxima nitebantur, et assidue malleolos atque incendiaria tela torquentes, laborabant in cassum, ea re quod umectis coriis et centonibus erant opertae materiae plures, aliae unctae alumine diligenter, ut ignis in eas laberetur innoxius.
The Persians, too, when the height of the mounds had already become great, stricken with horror of the huge ram, which other smaller ones followed, all strove with might and main to set fire to them, constantly hurling firebrands and blazing darts. But their efforts were vain, for the reason that the greater part of the timbers were covered with wetted hides and rags, while in other places they had been carefully coated with alum, so that the fire fell on them without effect.
