[M. Demetrius]

Of course -olus, -ulus is a diminutive, the most famous probably caliga Caligula. It just struck me funny, that's all, and no disprespect intended.

Modern era German historians, of course! There are many. Ancient German historians, well, in a forest-dwelling 1st Century mostly illiterate culture, there may have been some, but their oral histories did not survive the millennia.
