The text is now owned by Harvard University’s Sackler Museum. It was given to Harvard in 1984 by Beatrice Kelekian, who donated it in memory of her husband, Charles Dikran Kelekian. Charles’ father, Dikran Kelekian (1868-1951), was “an influential trader of Coptic antiquaries, deemed the ‘dean of antiquities’ among New York art dealers,” Luijendijk wrote in her book.
It is not known where the Kelekians got the gospel. Luijendijk searched the Kelekian family archive but found no information about where the text came from or when it was acquired.
