_Watchman_ CLYTÆMNESTRA AGAMEMNON _Chorus of Argive Elders_ _Herald_ (TALTHYBIOS) CASSANDRA ÆGISTHOS _ARGUMENT.—Ten years had passed since Agamemnon, son of Atreus, king of Mykenæ, had led the Hellenes to Troïa to take vengeance on Alexandros (also known as Paris), son of Priam. For Paris had basely wronged Menelaos, king of Sparta, Agamemnon's brother, in that, being received by him as a guest, he enticed his wife Helena to leave her lord and go with him to Troïa. And now the tenth year had come, and Paris was slain, and the city of the Troïans was taken and destroyed, and Agamemnon and the Hellenes were on their way homeward with the spoil and prisoners they had taken. But meanwhile Clytæmnestra too, Agamemnon's queen, had been unfaithful, and had taken as her paramour Ægisthos, son of that Thyestes whom Atreus, his brother, had made to eat, unknowing, of the flesh of his own children. And now, partly led by her adulterer, and partly seeking to avenge the death of her daughter Iphigeneia, whom Agamemnon had sacrificed to appease the wrath of Artemis, and partly also jealous because he was bringing back Cassandra, the daughter of Priam, as his concubine, she plotted with Ægisthos against her husband's life. But this was done secretly, and she stationed a guard on the roof of the royal palace to give notice when he saw the beacon-fires, by which Agamemnon had promised that he would send tidings that Troïa was taken._ _Note._—The unfaithfulness of Clytæmnestra and the murder of Agamemnon had entered into the Homeric cycle of the legends of the house of Atreus. In the _Odyssey_, however, Ægisthos is the chief agent in this crime (_Odyss._ iii. 264, iv. 91, 532, xi. 409); and the manner of it differs from that which Æschylos has adopted. Clytæmnestra first appears as slaying both her husband and Cassandra in Pindar (_Pyth._ xi. 26). SCENE.—Argos. _The Palace of_ AGAMEMNON; _statues of the Gods in front. Watchman on the roof.
