Agamenon
By leaving Agamenon for Troy he had promised Clitemnestra that I would announce by fire the take of the city the same day it happened. Since then, Clitemnestra had a servant who was to be in the observation for the signs. The atalaya sees the bonfire, and runs to announce it to Your lady. Which, with that new one, comes to the elders who make up the chorus of this tragedy and communicates the happy event.
