Thietmar of Merseburg was a bishop in northern Germany in the late 900s and early 1000s, and wrote a history of the events in his area. Because of his prominent position, historians have always been interested with his work because it's very possible he was an eyewitness to important events in the imperial court. I've finally gotten around to reading it (I tried tackling the original Latin years ago, but he clearly had no skill in that language and I got a headache after just a few pages), and this is literally on the second page:

Dear reader, know that the initial foundation and building up of the city [Merseburg] and its territory were undertaken by the people of Romulus who were formerly led here by Julius Caesar, the all powerful son-in-law of Pompey who was illustrious in both capabilities.

There then was a footnote by the translator:

Illustrious in both body and mind. Julius Caesar was actually the father-in-law of Pompey as the latter had married his daughter Julia. Thietmar's assertion that Merseburg owed its foundation to the Roman is a bald-faced lie probably intended to give his see a history comparable to those of the much older dioceses of the Rhineland.

Well, we're off to a good start. Literally opening up the work with historical inaccuracies and falsehoods.
