For instance, see Augustine, Ser. 252, 310, 311, and Ep. 22 and 29.9. In the latter he explains the origins of feasts dedicated to the martyrs as an antidote to other, less decorous feasts. Also see Augustine, Confessions 6.2, where he describes Monica’s practice of bringing cakes, wine and bread to oratories built in memory of the martyrs. In Cont. Faust. 20.21, Augustine refutes Faustus’s claim that Christians worshiped their saints like idols, offering them gifts of food and wine. Other sources include Tertullian, De resurrectione carnis 1; Ambrose, De Elia et Jejunio 17; and Paulinus of Nola, Ep. 13, 11–13, and Poema 27.
