Hexaemeron (Jacob of Serugh)
In the late 5th or early 6th century, Jacob of Serugh wrote his Homilies on the Hexaemeron, being the first known commentary on the Genesis creation narrative (that is, a Hexaemeron) in the Syriac language. This work was composed of seven homilies in total, with each homily being dedicated to one of the seven days.
Jacob opens his poetic homily with a prayer asking God to give him the ability to write about something that is beyond human speech. Jacob insists that God is the creator of all things and that creation occurred ex nihilo.
