The fact that his men killed Helios'kine was first reported by Lampetie to Helios, Who convinced Zeus to punish them. Odysseus says that he learned all this from Calypso who claims to have recieved her information from Hermes.
I think it is imagery because it makes you imagine what it looks like, but it could be slant rhyme because the last word in each line rhyme. I would personally go with imagery but I'm not sure. -- Hope this helps
