Harbison adds, "A detailed study of the literature on Gallarus reveals that the opinions of earlier authors were taken over almost in their entirety by later writers, who apparently never stopped to consider whether what they were copying from earlier accounts was founded in fact. The notion that Gallarus is one of the earliest church buildings in Ireland began with Smith in 1756 and is still current...these old ideas have cemented themselves into almost complete acceptance."
