Juturna

• book 10, book 12
• like Thetis in the Iliad
• an immortal caught between the worlds of Fate, divine manipulation and love for her mortal family
• her immortality is a gift from Jupiter as the 'price of her ransomed virginity'
• she is a victim on all counts
• raped by Jupiter
• blackmailed by Juno
• given immortality which consigns her to eternal grieving for her brother
• Virgil could've used any deity to help Turnus
• using his sister allows him to inject a greater element of human pity
• this is no Olympia acting in divine pique
• it is a sister desperately trying to save her brother
