Final answer:
Agamemnon does not readily agree that taking Briseis was an act of madness; instead, his action causes a dispute with Achilles in Homer's Iliad, making the claim False.
Step-by-step explanation:
Agamemnon does not readily agree that taking Briseis was an act of madness. Agamemnon, a character in Homer's epic poem the Iliad, was the king who led the Greek forces in the Trojan War. Briseis was a war prize given to Achilles, but Agamemnon took her from him, causing a dispute between the two warriors. There is tension and anger, rather than a quick admittance of folly by Agamemnon regarding the act. Therefore, the statement that Agamemnon readily agrees that taking Briseis was an act of madness is False.
