Санта-Мария-дельи-Анджели-э-деи-Мартири
Diocletian windows are named after the windows found in the Baths of Diocletian (AD 302) in Rome. (The Thermae is now the church of Santa Maria degli Angeli e dei Martiri.) The variant name, thermal window, also comes from their association with the Thermae of Diocletian.
