MAGNA MATER, SACELLUM
annually, on 27th March, the sacred black
stone of the Magna Mater was brought from her temple on the PALATINE
(q.v.) to the brook Almo, the modern Acquataccio, where this crossed
the via Appia south of the porta Capena, for the ceremony of lavatio.
Although there are numerous references to this ceremony, there is no
evidence for the existence of any kind of sacred edifice, and there was
probably only a locus sacratus (Cic. de nat. deor. iii. 52; Ov. Fast. iv.
