„For his chaste Muse employ'd her heaven-taught lyre
None but the noblest passions to inspire,
Not one immoral, one corrupted thought,
One line which, dying, he could wish to blot.“
— George Lyttelton, 1st Baron Lyttelton British politician 1709 - 1773
Prologue to Thomson's Coriolanus; reported in Bartlett's Familiar Quotations, 10th ed. (1919).
