An additional manuscript (A: Cambridge, Fitzwilliam Museum, CFM 20, olim Ashburnham, Barrois 16) was long considered to be another surviving copy of this text, but has since been determined to be a copy of the twelfth-century Compilation of St. Albans, one of the Prose Alexander's sources; Ross, D. J. A. (1985).
Ytterligare ett manuskript (A: Cambridge, Fitzwilliam Museum, CFM 20, olim Ashburnham, Barrois 16) ansågs länge vara ytterligare en överlevande kopia av texten, men har sedan bestämts vara en kopia av 1100-talstexten Compilation of St. Albans, en av Prose Alexander's källor; Ross, D. J. A. (1985).
