The play's the thing

In Philadelphia for IETF 71, and saw Wittenberg at the Arden. In mixing historical figures with the fantastic, this play ploughs similar ground to Christopher Columbus (or did you say sphere?), which I saw in Cleveland last year, with Faustus and Columbus being similar meaty heart-of-the-party roles, but Wittenberg is rather... wittier. And its run has just been extended.
