If you offer to the stage any thing unattempted, and venture to form a new character; let it be preserved to the last such as it set out at the beginning, and be consistent with itself. It is difficult to write with propriety on subjects to which all writers have a common claim; and you with more prudence will reduce the Iliad into acts, than if you first introduce arguments unknown and never treated of before. A public story will become your own property, if you do not dwell upon the whole circle of events, which is paltry and open to every one; nor must you be so faithful a translator, as to take the pains of rendering[ the original] word for word; nor by imitating throw yourself into straits, whence either shame or the rules of your work may forbid you to retreat.
