More recently, radically minded scholars have begun questioning the unity of concepts imposed by the term 'holy well'. In a paper in the "Living Spring Journal", Jeremy Harte distinguishes between early Anglo-Saxon 'holy wells' and those Christianised in the late Middle Ages, and argues 'apart from being venerated and being wet, they have little in common'; Harte has also stressed that limited evidence may mean scholars are considerably overestimating the number of holy wells which were active at any one time.
