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.
Damocles According to the story, Damocles was pandering to Dionysius, his king, and exclaimed to him that Dionysius was truly fortunate as a great man of power and authority, surrounded by magnificence. In response, Dionysius offered to switch places with Damocles for one day so that Damocles could taste that very fortune firsthand. Damocles quickly and eagerly accepted the king's proposal. Damocles sat down in the king's throne surrounded by every luxury, but Dionysius arranged that a huge sword should hang above the throne, held at the pommel only by a single hair of a horse's tail. Damocles finally begged the king that he be allowed to depart because he no longer wanted to be so fortunate, realizing that with great fortune and power comes also great danger.[1][2]
