Attestations from sources in English: 

Neixcuitilli was a term for "a new performance genre, but one possessing continuities with earlier Nahua forms and not quite the equivalent of 'drama' in the European sense." It was a didactic type of theater, and Spaniards described it as a "theater of evangelization." But, "it may have seemed to the observers as though Christian personae had entered their presence and taken on Nahua identities."
