Image of Edessa
The Byzantine Empire often tried to retake Edessa, especially under Romanos I Lekapenos, who obtained from the inhabitants the "Image of Edessa", an ancient portrait of Christ, and solemnly transferred it to Constantinople, August 16, 944. This was the final great achievement of Romanus's reign. This venerable and famous image, which was certainly at Edessa in 544, and of which there is an ancient copy in the Vatican Library, was looted and brought to the West by the Republic of Venice in 1207 following the Fourth Crusade. The city was ruled shortly thereafter by Marwanids.
