MATER DEUM, AEDES
a shrine of Cybele in the circus Maximus, mentioned in the Notitia (Reg. X), and by Tertullian (de spect. 8: frigebat daemonum concilium sine sua Matre: ea itaque illic praesidet Euripo). The reliefs representing the circus (cf. HJ 138, n. 68) and a mosaic (at Barcelona, cf. ib. n. 69) represent Cybele sitting on a lion on the spina of the circus, just east of its centre (HJ 131, 40 ; RE iii. 2574; Rosch. ii. 1667-1668).
