Rudolphus

Rudolphus is the Latinized form of the Germanic given name Rudolph (or Rudolf). It appears in Latin-language texts from late antiquity through the early modern period as an equivalent for the person's name in Germanic-speaking regions. The name itself derives from Old High German Hruodulf, composed of hruod “fame” and wulf “wolf.”

In medieval and early modern chronicles, Rudolf/Rudolphus would be rendered as Rudolphus in Latin. It was commonly used for rulers, clerics, and scholars from German-speaking areas, as Latin-language documents often Latinized local names.

Because Rudolphus is a Latin rendering rather than a separate name, many historical figures named Rudolf or Rudolph are referred to as Rudolphus in Latin sources. The form is also seen in hagiography for saints named Rudolf.

Today, Rudolphus is primarily encountered in scholarly or fictional contexts and is not commonly used as a native given name in contemporary Germanic-speaking communities.
