Титмар Мерзебургский
As the last member of the Burgundian Welfs, Rudolph was considered a weak ruler by his contemporaries. The chronicler Wipo of Burgundy called him effete; according to Hermann of Reichenau, his rule was marked by idleness and chaos. Thietmar of Merseburg named the Burgundian counts the actual rulers, while Rudolph only held the royal title.
