Cover Story: We revised the rich historical seismicity of Lefkada Isl., Ionian Sea, Greece, by utilizing a variety of little-known and published macroseismic information sources. A new descriptive and parametric catalogue was organized for the time interval from the 15th century A.D. up to 1911. The descriptive part of the catalogue includes information on the earthquakes’ impact on the anthropogenic and the natural environments. The parametric part includes revised earthquake focal parameters.  The catalogue is likely complete for lower magnitude threshold 6.0. A large puzzling earthquake examined ruptured the Strait of Otranto and supposedly damaged an unprecedentedly extensive region in Italy and Greece on 9/20 February 1743. Little-known documents revealed that the heavy destruction reported in Lefkada was very likely due to amalgamated information from local earthquakes and the large one. View this paper
