Mystery Monday: Riskipoe

Every Monday we will post an entry that hasn’t yet been published with a view towards harnessing the collective onomastic power of the internet. If you have any thoughts about the name’s origin, other variants it might be related to, other examples of its use, etc., please share them in the comments! If you wish to browse other Mystery Monday names, there is an index.

Today’s name is a 9th C masculine name from the Redon Cartularies. Because it doesn’t resemble any other name that we’re familiar with, we’re going to assume that this means it’s Breton in origin. 🙂


Anyone want to offer another suggestion? If you’ve got any thoughts, please share them in the comments!

    Always on the Germanic side, this is a possible interpretation as a dithematic name formed of the (rare!) prototheme risc “agile, fast” (related to Modern German rasch) and the deuterotheme boj “Boi (a tribe),; boy; Bavarian (another tribe and a state of Germany)”.

    I must admit that this interpretation is weak for some reasons: The prototheme Risc is really rare (only two examples in Förstemann 1900) and Boj is attested in monothematic names and sometimes as a prototheme, but Förstemann (1900) does not list it as a deuterotheme.

    Note that the name also appears in the charters as Riskiboe 864 and Rischiboe 866. If this is a dithematic Breton name, the deuterotheme may perhaps also be seen in Erispoe, the name of the duke of Brittany in 852, who has a Wikipedia entry.
