Behind the palace, unobserved and free, / there stood a door, a secret thoroughfare / through Priam's halls. Here poor Andromache / while Priam's kingdom flourished and was fair, / to greet her husband's parents would repair / alone, or carrying with tendance fain / to Hector's father Hector's son and heir.
