The «Historia compostellana» (XIIth century), a famous Spanish
medieval literary work, contains several place name references which have either
not yet been identified or the locations of which are in doubt. The aim of this
article is to identify and specifically locate a dozen or so of these place names,
amongst which we find «Orzelione» and «Sª Mª de Octaris», places about
which there has been special discussion. The author used his own methods in
conducting this research, which combined the extrinsic comparison of the place
names together with the intrinsic study of the related documents.
