Nor may they choose their partners voluntarily even from the ranks of the defeated, but must submit to random pairing at a Festival of Roses.
The Greeks do not understand why the Amazons refuse to form an alliance or, when battle is resumed, why Penthesilea so single-mindedly pursues Achilles.
Achilles enters the Amazon camp in search of Penthesilea despite the orders of Odysseus to return to the Greek army, and finds her unconscious in the arms of her devoted friend Prothoe; he explains to Prothoe that he has fallen in love with Penthesilea and wishes to marry her.
When Penthesilea regains consciousness, she is led to believe that she was the victor in their personal combat and that therefore she can claim him as her husband.
The Archpriestess curses the Queen for betraying the race, having put personal desires before duty.
Meanwhile, Achilles, realising that he must be conquered by Penthesilea, sends her (via a herald) a challenge to single combat, and goes unarmed to meet her.
