The correct answers: Soothsayer and Calpurnia
Calpurnia - Caesar's better half. Calpurnia accepts and puts alot of significance in signs and omens (things anticipated for what's to come). She cautions Caesar against heading off to the Senate on the Ides of March, since she has had repulsive bad dreams and has heard reports of numerous awful signs. In any case, Caesar's aspiration eventually makes him ignore her recommendation
Soothsayer - cautions Julius Caesar to be careful with March fifteenth (Ides of March - the day that he is killed). Julius Caesar calls the seer a visionary and overlooks his notices.
