Note 553 — Chapter XII · THE LATER REIGN OF WILLIAM IN NORMANDY.[159] 1051–1066. (continued 2)
Reading edition
See the note of Pertz, iii. 623, on Richer, iii. 77. The invasion of Otto (see vol. i. p. 265) and the exploits of Geoffrey (see vol. ii. pp. 274, 591) are transferred to the reign of Robert, “Robertus filius Ducis”—a confusion, one would almost think, between Robert the son of Hugh Capet and the elder Robert the son of Robert the Strong.
