Final answer:
Marpessa chose Idas as her lover because he was a mortal, a strong protector, and offered a more simple life compared to Apollo.
Step-by-step explanation:
In Greek mythology, Marpessa chose Idas as her lover rather than Apollo for a few reasons. First, Idas was a mortal like Marpessa, while Apollo was a god. Marpessa may have felt a stronger connection and sense of equality with Idas. Second, Idas was a strong and brave warrior who protected Marpessa, while Apollo was often portrayed as unpredictable and fickle. Marpessa likely valued the stability and loyalty that Idas offered. Finally, Marpessa's choice may have been influenced by her desire for a more simple and grounded life with Idas, rather than the glamorous and extravagant life that would come with being Apollo's lover.
