How to pronounce“mythos”in English

“POLY′MYTHY (S[ubstantive]) in Poetry, a fault in an epic poem, when inſtead of a ſingle mythos, or fable, there is a multiplicity of them.”

“[T]he critics above named, define in a general manner a mythos as the exposition of a fact, or of a thought, under the historical form—it is true; but yet, under the form stamped upon it by the symbolical genius and language of antiquity, so full of warmth and imagination. At the same time, mythoses have been distinguished into different kinds. The mythoses of history, that is to say, the recital of real events colored only by the ancient opinions, which confounded the divine with the human, the natural with the supernatural,—also the philosophic mythoses, those in which a simple thought, a speculation contemporaneous, or a novel idea are enveloped.”
