there happened such an extraordinary frost, that, at Constantinople, both seas were frozen for an hundred miles from the shore; the ice being covered with snow twenty cubits deep, and sufficiently strong to bear the heaviest carriages. When the frost broke, mountains of ice and frozen snow, being driven by the wind through the straits, did a great deal of damage to the walls of Constantinople. The month following, several prodigies appeared, or were thought to appear, in the air. At the same time a comet, which the Greeks called _Docites_, because it resembled a beam, was seen for ten days in the east, from whence it moved into the west, and shone there for one and twenty days more. The people were struck with terror and amazement at the sight of the prodigies, and apprehended the last day to be at hand.[22] Dreadful earthquakes, strange phenomena in the heavens, inundations, &c. occurred in the year 812, during the reign of Michael Balbus; but no remarkable plague is mentioned by the Greek historians, till the year 1025, when a new train of calamities took place. The plague broke out in Cappadocia, raging with such violence there, as well as in Paphlagonia and Armenia, that the people were forced to abandon their dwellings. A terrible famine followed; after which the earthquakes again commenced with redoubled fury: at Constantinople they continued forty days together; while people were terrified by a _comet_ (probably a large meteor) which passed with a dreadful noise from north to south; the whole horizon appearing to be in a flame.
