Zutphen (Gelderland), Netherlands
 This figure is now in the library of the church of St Walpurgis which 
      was founded around 1100, 
      and has since been altered and partially destroyed. The library was added 
      in 1550. 
      After the Reformation the church changed from Catholic to Protestant 
      (like most in the United Provinces, where Catholic places of worship were 
      actually hidden) 
      but the library remained, though many of its books were destroyed.

The culs-de-lampe or bracket-corbels of the library show religious 
      themes, 
      apart from this one which was removed at some time in the past to prevent 
      shock and offence.
One of the old dark-red tiles of the library floor shows a dog's footprint 
      - said to be that of the Devil - 
      which may (or may not) have a bearing on this amazing sheela-na-gig 
      carving, which,
      from appearance alone, could date from any time between 1150 and 1550.
The vulva is deeply-incised, and the figure (like that at Marienhafen in NW Germany) is of the Saint-Vivien type.
