Note 822 — Chapter XII · THE WORSHIP OF MITHRAS
Reading edition
Op. cit. II. p. 336, reproduced in the article in the P.S.B.A. quoted in n. 2, p. 237 supra. In the collection of busts of the gods on the arch surrounding the Tauroctony at Bologna, the head of Zeus wearing the modius of Serapis appears with six others who, reading from left to right, are the Sun, Saturn, Venus, Jupiter, Mercury, Mars and the Moon. Although Jupiter here occupies the centre and place of honour, it is probable that both he and the other gods are here merely symbols of the planets. See Cumont, op. cit. II. p. 261 and Fig. 99.
