Amata
The wife of king Latinus and mother of Lavinia, who, when Aeneas sued for the hand of the latter, opposed him, because she had already promised Lavinia to Turnus. At the same time she was instigated by Alecto, who acted according to the request of Juno, to stir up the war with Turnus. This story fills the greater part of the seventh book of Virgil's Aeneid. When Amata was informed that Turnus had fallen in battle, she hung herself.
From Smith's Dictionary of Greek and Roman Biography and MythologyFrom The Aeneid by Virgil Book VII
Smear'd as she was with black Gorgonian blood, The Fury sprang above the Stygian flood; And on her wicker wings, sublime thro' night, She to the Latian palace took her flight: There sought the queen's apartment, stood before The peaceful threshold, and besieg'd the door. Restless Amata lay, her swelling breast Fir'd with disdain for Turnus dispossess'd, And the new nuptials of the Trojan guest. From her black bloody locks the Fury shakes Her darling plague, the fav'rite of her snakes; With her full force she threw the poisonous dart, And fix'd it deep within Amata's heart, That, thus envenom'd, she might kindle rage, And sacrifice to strife her house husband's age.
