The ancient art found in Menoa's office is quite striking, and it foreshadows the rest of the movie. The figures are Eos and her son Memnon, who had died fighting Achilles in the Trojan War. In her grief, she flies him to Olympus and begs Zeus to make her son immortal to save him. Menoa is in a perpetual state of grieving from losing Morphomon, and seeks to prevent others from having the same fate by "immortalizing them", so it's fitting for her to have this art in her office.
