Fragmenta Historica Tusculana provides both a date,
6 July, and a year – 551 CE. It recounts that “a great and
terrible earthquake happened in all the Eastern region, that
is, in Arabia, the whole of Palestine, and in the land of
Mesopotamia and of Antiochia, and many cities of the
Phoenician littoral collapsed, viz. Tyre, Sidon, Berytus,
Tripolis, Biblus (sic), and Botrys, and other cities; and of
the surrounding villages 101 fell, and multitudes of men were
crushed in these cities.” It also reports a rockslide in Botrys.
