This map is an improved version of one that appeared in my PhD thesis (Millington, 2002, pp.269-270, Map 13), generated using the Scripts Explorer. The scripts database has grown slightly since 2002 (Millington, 1994-2006).
The Plough Plays of the English East Midlands include some lines from Saint George plays, and sometimes George himself makes an appearance. These lines have strong links with the Northern English group of plays. However, there a few lines, such as the couplet in this map that also suggest a tenuous link with the Cotswold group of plays.
