The excerpt "Few men can keep alive through a big surf to crawl, clotted with brine, on kindly beaches in joy, in joy, knowing the abyss behind: and so she too rejoiced, her gaze upon her husband, her white arms round him pressed as though forever" is taken from the part of Odysseus's epic journey known as his return home.
The lines "He dropped his eyes and nodded, and the prince Telemachus, true son of King Odysseus, belted his sword on, clapped hand to his spear, and with a clink and glitter of keen bronze stood by his chair, in the forefront near his father" support the theme of teamwork building strength and unity.
Note: It seems there was an overlap in the questions, and the last part of the question regarding the theme does not align with the second excerpt provided. Please let me know if there's anything else I can help you with.
