Read the excerpt from "the discovery of oz, the terrible." "no one knows it but you four—and myself," replied oz. "i have fooled everyone so long that i thought i should never be found out. it was a great mistake my ever letting you into the throne room. usually i will not see even my subjects, and so they believe i am something terrible." "but, i don't understand," said dorothy, in [confusion]. "how was it that you appeared to me as a great head? " "that was one of my tricks," answered oz. "step this way, , and i will tell you all about it." he led the way to a small [hallway] in the rear of the throne room, and they all followed him. he pointed to one corner, in which lay the great head, made out of many thicknesses of paper, and with a carefully painted face. what shaped dorothy's initial perspective of the wizard? the wizard used tricks to fool dorothy and her friends. the wizard refused to let dorothy into the throne room. the wizard showed dorothy the a head made of paper. the wizard came out from behind a secret screen.
