This thesis concerns those English folk plays whose plots are centred on the
quack doctor character. Earlier researchers proposed three possible origins for
these plays: (a) a non-specific mystery play from the time of the crusades, (b)
some pre-Christian fertility ritual, and (c) primitive shamanism. All three
proposals were based on over-general comparisons, and relied on the key assumption
that a continuous history can be traced back from before modern plays to the
relevant era. However, in contrast with other customs, no evidence can be found
for these plays before the 18th century, despite diligent searching. These
theories are therefore disproved.
Instead, it is proposed that the plays were attached in the early to mid 18th
century to existing house-visiting customs. These were probably the source of
the non-representational costumes that are sometimes worn. There is also
evidence for the influence of the conventions of the English Harlequinade. The
provenance of the scripts is unknown, but similarities between them suggest they
ultimately derived from a single proto-text.
A full-text database of 181 texts and fragments was built for investigation
using cluster analysis, distribution mapping and other computerised techniques,
some of which are novel. The cluster analysis has generated a
new classification for the play texts that both confirms and extends the
established typology. Comparison of the attributes of the clusters, aided by
distribution mapping, has resulted in a putative genealogy
for the plays that is presented for discussion.
Trellis graphing has revealed a core of common lines that can be assembled
into a viable script. This represents a reconstructed
proto-text, although it requires consolidation with further evidence.
Bibliometric analysis suggests that more archival research is needed in the
century ending about 1750, which is the key period for the genesis of the plays.
