The Hexaemeron of Jacob of Edessa (d. 708) is Jacob's commentary on the six days of creation of the Genesis creation narrative. Jacob worked on it in the first few years of the eighth century, as it was his final work. Unable to complete it within his own lifetime, the work was finished by his friend George, Bishop of the Arabs (d. 724).[1] It is an example of a work in the genre of Hexaemeral literature, but should not be confused with a similar earlier work, namely the Hexaemeron by Jacob of Serugh.
