Concerning the Sicilian Strait, apart from what many other writers have written, this author states that a portentous occurrence takes place: the billows, he says, being carried with a loud whistling sound from the Tyrrhenian Sea, dash against both the promontories, that of Sicily and that of Italy, which is called Rhegium, and being borne from a great sea are shut up in a narrow space; and when this occurs they raise the waves with a loud roar in mid air to a very great height, as they dash upwards, so that the rising of the waters is visible to those who are far away, not resembling the rising of the sea, but white and foaming, and similar to the sweeping movements which take place in excessively violent storms: and that sometimes the waves meet each other on both the promontories and produce a collision incredible in description, and unendurable for the eyes to behold; but at other times parting, after dashing against each other, they show an abyss, so deep and horrible to those who are compelled to look on, that many are unable to restrain themselves, and fall, blinded with terror.
