Tiburtina vero et quae eodem genere sunt omnia, sufferunt et ab oneribus et a tempestatibus iniurias, sed ab igni non possunt esse tuta, simulque sunt ab eo tacta, dissiliunt et dissipantur, ideo quod temperatura naturali parvo sunt umore itemque non multum habent terreni, sed aeris plurimum et ignis.
Travertine, however, and all stones which are of the same kind, withstand injury from heavy loads and from storms; but from fire they cannot be safe; as soon as they are touched by it they crack and break up. And the reason is that by the nature of their composition they have little moisture and also not much earth, but much air and fire.
