Such a detailed account does not exist, of course. The name "Gobbo" is an interesting, and sensible choice since it means "hunchback" in Italian. The character Charlemagne explains its etymology in harsh terms: "Gobbo means hunchback... The men picked the word up in Italy, when we fought the Lombards the year you were born. When I heard my son called Gobbo I knew he must not succeed me. No king must be mocked. Besides... I fear that Gobbo is not entirely to be trusted." This, then, is yet another possibility (and, though it is founded in little historical evidence, it makes intuitive sense) for Charlemagne's changing his heir. However, it seems that the king's prophetic concerns about Pepin's trustworthiness are little more than a literary device. Pepin's relationship with his father was probably fairly strong in his early years, according to most of the available sources.
