This chapter covers a large literary category which I call ‘hagiographical’: it includes miracle stories that involve the Virgin Mary, full-length Lives of the Virgin (which began to be produced from the late eighth or early ninth century onward) and two Apocalypses. Many of the texts studied here are composed in a colloquial style that may have appealed to wider audiences in non-liturgical settings. This genre thus contrasts with the liturgical texts that are studied in the first four chapters: according to hagiography, Mary assumes power and agency that goes beyond her theological role in giving birth to Christ. Christians appeal to this female holy figure as one who is able to appeal to Christ and who is willing to help sinners or supplicants who despair of God’s direct favour. Christological teaching persists in these texts, but the emphasis has shifted to Mary’s intercessory role among Christians.
