Final answer:
Neptune is the speaker in the excerpt, expressing anger at Ulysses for reaching Ithaca safely.
Step-by-step explanation:
The speaker in this excerpt from book 13 of Homer's Odyssey is Neptune (also known as Poseidon). From the tone of the excerpt, one can infer that the speaker, Neptune, displays a sense of anger and frustration at seeing Ulysses (Odysseus) reach Ithaca safely. He expresses resentment about the perceived lack of respect and honour he feels he deserves as a deity when his vengeance is thwarted, indicating a bruised ego and an irate disposition, particularly directed towards the Phaeacians for aiding Ulysses and towards Ulysses himself.
