Medea, by Euripides - (translated by: T.A. Buckley)

So much then I wish to obtain from you, if any plan or contrivance be devised by me to repay with justice these injuries on my husband, and on him who gave his daughter, and on her to whom he was married,[13] that you would be silent; for a woman in other respects is full of fear, and timid to look upon deeds of courage and the sword; but when she is injured in her bed, no other disposition is more blood-thirsty.†

Strong necessity compels me, O aged man, for this the Gods and I deliberating ill have contrived.†
