It rather depends on what you mean by "medieval". The publisher
offers "sample text" at:
Of the seven items shown, three belong to a largely post-medieval
period: Cromwell, Elizabeth I, Wild Geese.
The other four entries are: Banshee, Ceasair, Patrick, Tara -- all
of which are treated in considerably more detail in the Oxford
_Dictionary of Celtic Mythology_, which has long since been available
in paperback at a very reasonable price.
