Note 30
3RD Cause of the Destruction of Rome From Chapter 71 of the Decline & Fall

I shall quote the authentic testimony of the Saxon poet (A.D. 887-899), de Rebus gestis Caroli magni, l. v. 437-440, in the Historians of France (tom. v. p. 180):

Ad quæ marmoreas præstabat ROMA columnas,
Quasdam præcipuas pulchra Ravenna dedit
De tam longinquâ poterit regiona vetustas
Illius ornatum Francia ferre tibi.

And I shall add from the Chronicle of Sigebert (Historians of France , tom. v. p. 378),

extruxit etiam Aquisgrani basilicam plurimæ pulchritudinis, ad cujus structuram a ROMA et Ravenna columnas et marmora devehi fecit.
