“Am I really, Neptune, to take this daring and unyielding message to Jove, or will you reconsider your answer? Sensible people are open to argument, and you know that the Erinyes always range themselves on the side of the older person.”
~ The Iliad - Book XV (Samuel Butler Translation. p84 / v230)
Jove wakes up from sleep and sees the Trojans getting defeated at the hands of the Achaeans. He immediately realizes the deception of Juno. She blames Neptune. Jove asks Iris to go to Neptune and ask him to withdraw or face his wrath, and Apollo to give strength to Hector. Neptune withdraws. Hector is imbued with new strength. The Achaeans are surprised to see Hector and the army coming back. They had thought Hector had died with Ajax’s blow. Trojans cross the trenches, destroy the wall and reach the ships, ready to set fire to them. Book 15 is the most action-packed yet, while Book 9 (Phoenix’s speech to Achilles) was the most touching.
In book 15 of The Iliad, Jove asks Iris to ask Neptune to stop aiding the Greeks, or he will get punished. Iris conveys the message, and Neptune is enraged because his brother treats him disrespectfully. He immediately responds angrily, saying he will not let Jove lay hands upon him as though he were a nobody and is ready to fight. Iris is level-headed and asks Neptune to reconsider. Neptune thinks over, and the fight is averted.
