The coronation of the emperor, and some original ceremonies of the xth century are preserved in the Panegyric on Berengarius, (Script. Ital. tom. ii. pars i. p. 405 - 414,) illustrated by the Notes of Hadrian Valesius and Leibnitz. Sigonius has related the whole process of the Roman expedition, in good Latin, but with some errors of time and fact, (l. vii. p. 441 - 446.)
