The original ending may have been lost; among the possible reasons given are the accidental loss of the last page of Mark’s own first copy [the same defect, at a very early stage, in the case of the 18th book of the Κεστοί of Jul. Africanus: WBauer, Orthodoxy etc. (Engl. tr. of 2d German ed. ’64) ’71, 159ff.
