why does deianira send heracles the robe with nessus' blood on it
Nessus (mythology) Nessus is known for his role in the story of the Tunic of Nessus. After carrying Deianeira, the wife of Heracles, across the river, he attempted to force himself upon her. Heracles saw this from across the river and shot a Hydra-poisoned arrow into Nessus's breast. As he lay dying, as a final act of malice, Nessus told Deianeira that his blood would ensure that Heracles would be true to her forever, knowing the blood to be infected with the hydra's poison.
Theseus When Theseus arrived at Athens, he did not reveal his true identity immediately. Aegeus gave him hospitality but was suspicious of the young, powerful stranger's intentions. Aegeus's wife Medea recognised Theseus immediately as Aegeus' son and worried that Theseus would be chosen as heir to Aegeus' kingdom instead of her son Medus. She tried to arrange to have Theseus killed by asking him to capture the Marathonian Bull, an emblem of Cretan power.
