An epilogue is a section of writing at the conclusion of a written work.  

Ancient Near Eastern cultures would perform treaties between two parties known as Suzerain treaties. The treaty consisted of two parties one greater and the other a lesser.  As a part of the treaty the parties would write down the stipulations of the treaty. This written document was placed in the lesser’s temple and would remind them of the stipulations of the covenant when they read over it. To ratify the ceremony the body of animals were cut in two and placed side by side. The two parties would walk through the animals making a vow to one another that if the covenant was broken then what had happened to the animals would happen to the one who broke the covenant.
