Recent scholarship has maintained that the Dionysian rites of 2 Macc 6:7b are not historical because evidence of this cult in Seleukid official policy is seen as meager at best. A review of Antiochus IV’s coinage, his procession at Daphne, his designation of Geron the Athenian as enforcer of the imposed cult, and other allusions to promiscuity in the Temple may indicate that this reference to Dionysian practices is at least plausible.
