The Aethiopis (7th century BC) and a work named Posthomerica , composed by Quintus of Smyrna in the fourth century AD, relate further events from the Trojan War . When Penthesilea , queen of the Amazons and daughter of Ares , arrives in Troy, Priam hopes that she defeat Achilles. After his temporary truce with Priam, Achilles fights and kills the warrior queen, only to grieve over her death later.  At first, he was so distracted by her beauty, he did not fight as intensely as usual. Once he realized that his distraction was endangering his life, he refocused and killed her.
