English translation of the letter to King Louis VII from Guidoboni and Comastri (2005)
To Louis by the grace of God the most Christian king of the Franks, most dear lord and father, from Amalric, by the same grace of God king of Jerusalem, greetings.
Amidst the daily torments of our enemies, which have so weakened the eastern church that it is close to ruin, there has come an extraordinary disaster through
the just but hidden judgment of God. For on the day of the passion of the apostles Peter and Paul [29 June],
a terrible earthquake suddenly and unexpectedly
reduced the city of Tripoli to ruins, killing almost everyone who was there. It also shook Margat, Gabulum [Gabala] and Laodicea, and almost all the castles
and towns between Tripoli and Antioch in such an amazing and indescribable way that no trace of buildings can be seen. In Antioch, too, quite apart from the
fact that houses and other buildings were torn apart and almost all reduced to ruins, so that we are bound to speak with a deep groan of grief, town walls were
damaged to such an extent that they seem to be beyond repair, and indeed they are. The result is that Antioch and Tripoli and their dependent provinces will be
occupied by the enemies of the Cross of Christ, if Tripoli, Archas [Archis], Gibellum [Gibelacar], Laodicea, Margat and Antioch do not receive clandestine aid.
But by the will of God, the land of the Gentiles is all laid waste, and their towns and fortresses have been more widely destroyed, not without some of their
people being killed.
