slay his opponents. Using this to seize the throne of Assyria he covets,
he then teaches the skull-cup rite to the Persians, and so calls them
‘Medes’ (M¯edoi) after ‘Medusa’ (Me˘dousa). The Gorgon-head as
described aligns well with a series of recipes for skull-cups (skyphoi)
found in a magical papyrus of the fourth century ad (PGM iv, 2006–
2125), and these give a good indication of the sort of rites that Malalas
will have envisaged. The recipes are incorporated into a fictional
letter to a Persian mage Ostanes from a Thessalian sorcerer Pitys,
who praises the skull-cup technique as the spell of choice for the
great magi of the past. One is to take a dead man’s skull and deploy
some obscure words of power to summon up the relevant ghost,
which will then present itself in one’s dreams, and which can be
employed as an all-purpose familiar. The ghost can instil sexual
desire, send dreams, or strike people down sick. How far does the
notion that the Gorgon-head was a magical object of this sort go back
in the tradition? It may already lurk behind Ovid’s Metamorphoses,
where Eryx, one of Phineus’ supporters, refers to the Gorgon-head
with the phrase ‘magical (magica) weapons’ (5.197, of 8 ad).
In a further development Perseus himself became a figure of
magical power to be conjured with. An imperial-period sardonyx
gemstone amulet against gout, in the Hermitage, shows Perseus
flying through the air with harp¯e and Gorgon-head. On the reverse is
inscribed: ‘Flee, gout, Perseus pursues you.’

It has been precariously contended that Perseus had an impact
on an indirect outgrowth of Zoroastrianism, the Mithraic mysteries,
the practice of which we first encounter in Cilicia in 67 bc (Plutarch
Pompey 24), an area, in subsequent centuries at any rate, strongly
devoted to Perseus. The central Mithraic cult image is of Mithras
killing the bull, the ‘tauroctony’: he turns away as he kills it, as
Perseus does when he kills the Gorgon, and, as Perseus sometimes
does, he wear a Phrygian cap. The cult image as a whole supposedly
reflects the fact that the constellation of Perseus hovers above the
constellation of Taurus. The name ‘Perses’ was given to the fifth
grade of initiation. Perseus’ myth is further held to have influenced
other aspects of Mithraic imagery, including its harp¯e, its lion-
headed god, supposedly recalling an early Gorgon, and its under-
ground chambers.
