ii) CRESCENTIUS [II] "Nomentanus" (-beheaded Rome 29 Apr 998). "Johannes et Crescentius…germani filii D. Crescentii olim consulis et ducis qui dicebatur de Theodora, seu Sergiæ…olim jugalium" are named in a charter dated 15 Oct 989[790]. Rodulfus Glaber records the rebellion of Crescentius against the emperor's authority over papal appointments and his capture by the emperor's forces and murder by being thrown from the ramparts[791]. The Gesta Mediolanensium records that "Crescentius" was beheaded "in prato Neroniano"[792]. Hugo´s Historia Farfensis records that "Crescentius" was killed during the wars between Emperor Otto III and Pope Gregory, dated to 29 Apr 998 by the editor of the MGH edition[793].

[m [THEODORA] [Stefania], daughter of --- (-[before 1006]). The Gesta Mediolanensium records that "Stephania…uxor eius traditur adulteranda Teutonibus" (referring to "Crescentius")[794]. Lyndsay Brook states that "a wife attributed to Crescentius, Stephania, is almost certainly apocryphal"[795], although it is unclear why the author thinks it unlikely that Crescentius [II] was married at all. She was named as deceased in a document dated 1006[796], although it remains to be clarified whether this is a reference to Theodora, widow of Crescentius [II]'s older brother Ioannes [I] Crescentius. [She married secondly (after Feb 998, divorced [998/1000]%29 Emperor Otto III. This alleged second marriage is unlikely to be correct. It is based on Rodulfus Glaber who recounts that Otto III married the widow of Crescentius Senator of Rome but "dismissed her by divorce" shortly afterwards[797]. No corroborative sources have been identified, and the report appears unlikely, not only because of what must have been an evident age difference between the parties but also the unlikelihood that the young emperor would appear to condone his enemy's treachery by marrying his widow.]

Ma nel 995 papa Giovanni XV (985-996) invocò l'aiuto del re, divenuto ormai maggiorenne, contro Giovanni Crescenzio, il quale da dieci anni dominava in Roma in qualità di patrizio... ...Il 21 maggio 996 Gregorio incoronò imperatore O., il quale accolse la sottomissione del patrizio e ritornò ad Aquisgrana persuaso d' avere assicurato la pace. Ma già al principio del 997 Crescenzio cacciò il papa, levandogli contro, con l'aiuto dei Bizantini,... ... Giovanni Crescenzio s'era asserragliato in Castel Sant'Angelo. Questo venne espugnato il 28 aprile 998, Crescenzio fu ucciso e il suo cadavere impiccato...
