Final answer:
The Golden Fleece hung in an oak grove sacred to the god Hermes, illustrating his significant status in Greek mythology and connection to sacred groves and animals such as the ram.
Step-by-step explanation:
The Golden Fleece hung in an oak grove sacred to the god Hermes. In Greek mythology, Hermes held various attributes and was known as a messenger god and god of commerce. The link between Hermes and the Golden Fleece is illustrated in ancient texts which discuss the god's connection to sacred groves and animals such as the ram, an animal often associated with him. He is also mentioned in the context of the Great Gods and his position in Mysteries. This evidence implies Hermes' significant status within the local cult and potentially his connection to the iconic Golden Fleece which features prominently in the Argonauts' quest.
