Note 3 — Aphrodisiacs and Anti-Aphrodisiacs:
Reading edition
In the church of St. Peter's at Rome, is kept, en secret, a large stone emblem of the creative power, of a very peculiar shape, on which are engraved Ζευς Σωτηρ. Only persons who have great interest can get a sight of it. Is it from this stone having some peculiar virtue that those preux chevaliers, the cardinals, keep it so closely? Perhaps they choose to monopolize the use of it? I never saw it, but I know that it was at St Peter's.—Higgins.
