Maxentius was acclaimed emperor in October 306 against the wishes of Maximilla's father, who unsuccessfully tried to overthrow the usurper in 307.

Valeria and her husband were together before his defeat at the Battle of the Milvian Bridge, after which she disappears from the historical record.

Valeria Maximilla's portrait does not appear on any of the coinage issued under Maxentius, but she may have been depicted on a defaced sculpture now housed in the Capitoline Museums.

[2] Maximilla may be the nameless queen who appears in the hagiography of St. Catherine of Alexandria by Jacobus de Voragine (one of the fantastic stories in the "Golden Legend").

[3] In another similar version by 15th-century Italian hagiographer Petrus de Natalibus, the queen was named "Faustina".
