The penthos ‘grief’ felt by the losing Achaeans is now compared, by way of a simile, to a seastorm brought by the North Wind and the West Wind personified respectively as Boreas and Zephyros, I.09.005: these winds come suddenly and violently from the direction of Thrace, blowing across the narrow strait of the Hellespont. See the comment on I.07.063–064. As the narrative of the Iliad advances, such a violent seastorm will become a fitting synonym also for the danger facing the Achaeans as their fortunes in war start giving way to the overwhelming momentum of the Trojan offensive led by Hector.
