Andrea Dandolo wrote about an earthquake in two separate passages, divided by two sentences. In the first account, he states that the East was shaken by so tremendous an earthquake that it completely destroyed buildings, especially in Cilicia, at Mamistra, and all the fortresses in the surrounding area, and in some places nothing was left standing, adding that men wandered through the fields, fearing that they would be swallowed up by the earth. No specific date was provided for this first earthquake. In the second passage, Dandolo reports that during the night of the Ides of November [13 November], in the suburbs of Antioch, the earth swallowed up many towers and the houses beside them, together with their inhabitants. Guidoboni and Comastri (2005) suggest that Dandolo drew on Marino Sanudo the Elder for the first account, and on Abbot Anselm of Gembloux for the second, as the phrasing is nearly identical—perhaps even verbatim. They propose that Dandolo mistakenly treated these as two separate events, when in fact both descriptions refer to the same earthquake of 13 November 1114 CE. Ambraseys (2009) likewise dates Dandolo’s account to 13 November 1114 CE.
