William II or Florence the Guardian?: Questions about a Tomb and a Skeleton in the Abbey Church at Middelburg Both William II, Count of Holland and Zeeland and King of the Holy Roman Empire (†1256, re-interred 1282) and his brother Florence the Guardian (†1258) are buried in the Norbertine abbey church in Middelburg. In 1817 a skeleton was found in a bricked up niche, along with the remains of a tombstone on which was carved a knightly figure whose shield bears the coat of arms of Holland. Based on the results of an examination of the bones by George J.R. Maat and his team (Leiden University Medical Centre), Henderikx takes it that the skeleton could be either that of the King of the Holy Roman Empire or of Florence the Guardian. Considering that the skeleton, burial space and tombstone formed a coherent whole, and the high-relief on the tombstone almost certainly does not refer to the King of Rome but to his brother, Henderikx concludes that the skeleton must be the earthly remains of Florence the Guardian.
