For nine days the deadly shower fell without ceasing; but on the tenth, Achilles summoned a general gathering of the host, to inquire into the causes of the calamity which had fallen on his countrymen. The chiefs met in full conclave, and about them were gathered the meaner sort in their tens of thousands. When the clamorous cries of the multitude were stilled, Achilles rose in his place, and addressing himself directly to Agamemnon said: "Son of Atreus, how long wilt thou suffer thy people to perish? Is it not enough that our blood is poured forth every day in battle with thy foes, but must pestilence also make havoc among our ranks? This is Apollo's work, and it is time to ask some priest or soothsayer how we have offended the god, that we may appease his anger with the fat of goats and lambs, and save ourselves from further harm." Among the elders sat Calchas, the chief seer of the Greeks; who knew all things--what was, and had been, and was to come--and was the chosen leader of the army in matters of religion. Seeing all eyes turned upon him he stood up and answered the challenge of Achilles, though with manifest reluctance and constraint. "Illustrious chieftain," he said, "thou hast asked the cause of Apollo's anger, and I know that thou lookest to me for an answer. But swear unto me first that thou wilt defend me in word and in deed; for I fear that, by revealing the counsels of the god whom I serve, I shall offend one who is the greatest and mightiest among us." "Tell us what thou knowest, and fear nothing," answered Achilles; "while I live no one shall lift his hand against thee, no, not Agamemnon himself." Thus encouraged, Calchas spoke out, and declared that the only means of staying the pestilence was by sending back Chryseis to her father, without price or ransom, and offering a costly sacrifice of atonement to Apollo in his temple at Chrysa. It was not without reason that the prudent seer had appealed to Achilles for protection; for no sooner had his words been uttered than Agamemnon sprang from his seat, with fury in his looks, and overwhelmed the prophet with a torrent of reproaches. "Ill fare thy prophecies, thou prophet of ill!" he cried. "Not one good word have I ever heard from thy lips; but this is the worst that ever thou hast spoken. Hard and bitter is the charge which thou hast laid upon me, bidding me restore this maiden, fairer and dearer to me than Clytæmnestra, my wedded wife. Nevertheless I will send her back, if I cannot save my people otherwise; but look ye to it, princes and councillors of Greece, that I find fit recompense for my loss; for she was a choice prize of war, set apart for me as a gift of privilege and honour."
