Although ubiquitous and informative, titles are not the only paratextual item that define Revelation’s manuscripts. An even more conspicuous force on the shape of Revelation’s interpretation and transmission is the commentary initially produced by the late sixth-/early seventh-century Archbishop of Cappadocian Caesarea, Andrew. This chapter maps the features of the late-antique Andrew of Caesarea commentary tradition, not only its explicit commentary, but also the prologue, kephalaia tables, epilogue, intertitles, and textual divisions. Different parts of the Andrew tradition appear in variegated ways in different manuscripts, but nearly half of all of Revelation’s Greek manuscripts maintain at least parts of the Andrew’s apparatus. Commentary manuscripts are a key part of the New Testament tradition that provide an array of information that informs reception-historical enquiry.
