Measure for Measure, Montmorency, and Sardou's La Tosca
In lieu of an abstract, the first paragraph of the essay follows:
Angelo in Measure for Measure is "criminal in double violation" (V.i.409): he tries to violate Isabel, and he breaks his promise to save her brother when he orders Claudio beheaded. Stories of such double criminals were surprisingly widespread in the sixteenth century, and most of them are mentioned in my recent New Variorum Shakespeare edition (New York: Modern Language Association of America, 1980). I can now add one more analogue that I found too late to mention there, and point out that Sardou claimed it as his source for La Tosca.
