Book 1 of the Odyssey begins with A an explanation how Trojan War started B invocation in which poet asks for inspiration from muse to tell story Odysseus?

Here's why:

* The Odyssey begins with a direct invocation to the Muse Calliope, the muse of epic poetry. Homer pleads with the muse to help him tell the story of Odysseus's journey home from the Trojan War.

* The Trojan War is a background event. While the Odyssey does detail events related to the Trojan War, it is not the focus of the first book. The story primarily focuses on Odysseus's absence and the struggles of his family in his absence.
