The play refers to the legendary history of St. Theophilus of Adana, who according to traditional saints' legends made a pact with the Devil and repented of it.
This play is the original source of an influential invocation to the Devil (in an unknown language). The original text from the French play is given to the character Salatin — apparently a version of Saladin — who in this play is labelled a sorcerer; Salatin uses these words to invoke the Devil:
(Ci conjure Salatins le deable.)
Bagahi laca bachahé,
Lamac cahi achabahé,
Lamac lamec bachalyos,
Samahac et famyolas,
Another French miracle play from the same time period by Jean Bodel, Jeu de Saint Nicolas, also contains an invocation to the Devil in an unknown language.
