Note 166 — Scene IV.—Interior of the Tower.
Reading edition
["Drove at midnight to see the Coliseum by moonlight: but what can I say of the Coliseum? It must be seen; to describe it I should have thought impossible, if I had not read Manfred.... His [Byron's] description is the very thing itself; but what cannot he do on such a subject, when his pen is like the wand of Moses, whose touch can produce waters even from the barren rock?"—Matthews's Diary of an Invalid, 1820, pp. 158, 159. (Compare Childe Harold, Canto IV. stanzas cxxviii.-cxxxi.)]
