Aeschylus 
Agamemnon [EPUB ebook] 

“Agamemnon” is the first of the three linked tragedies which make up “
The Oresteia” trilogy (comprising “Agamemnon”, “Choephori” and “The Eumenides”), the only surviving example of a complete trilogy of ancient Greek plays, by the ancient Greek playwright Aeschylus.
’Agamemnon’ was originally performed at the City Dionysia in 458 B.C.
’Agamemnon” describes the homecoming of Agamemnon, king of Argos, from the Trojan War, and his return to his wife, Clytemnestra, who had been planning his murder (in concert with her lover, Aegisthus) as revenge for Agamemnon‘s earlier sacrifice of their daughter, Iphigenia.
