Final answer:
Demeter is the goddess of harvest and agriculture, and Dionysus is the god of wine and festivity, both with deep roots in Greek religious practices.
Step-by-step explanation:
Demeter and Dionysus are renowned figures in Greek mythology, where Demeter is the goddess of harvest and agriculture, and Dionysus is the god of wine, vegetation, pleasure, festivity, madness, and wild frenzy.
They both play significant roles in religious practices and have various attributes and symbols associated with them; for instance, Demeter is often depicted carrying a torch and is intimately linked to the Eleusinian Mysteries and festivals such as the Thesmophoria.
Dionysus, on the other hand, is recognized not only for his association with wine but also in connection to performance art such as theatre and ritual madness, often symbolized by the grapevine.
