Saint Aelia Flaccilla

Aelia Flavia Flaccilla (died 386), better known simply as Aelia Flacilla or Flacilla, was a Roman empress and first wife of the Roman Emperor Theodosius I. She was of Hispanian Roman descent. During her marriage to Theodosius, she gave birth to two sons – future Emperors Arcadius and Honorius – and a daughter, Aelia Pulcheria. According to Laus Serenae ("In Praise of Serena"), a poem by Claudian, both Serena and Flaccilla were from Hispania. A passage of Themistius (Oratio XVI, De Saturnino) has been interpreted to identify Flaccilla's father as Claudius Antonius, Praetorian prefect of Gaul from 376 to 377 and Roman consul in 382. However the relation is considered doubtful. In 1967, John Robert Martindale, later one of several article writers in the Prosopography of the Later Roman Empire, suggested that the passage actually identifies Antonius as the brother-in-law of Theodosius. However the passage is vague enough to allow Afranius Syagrius, co-consul of Antonius in 382, to be the brother-in-law in question. The only kin clearly identified in primary sources was her nephew Nebridius, son of an unnamed sister. In 376, Flaccilla married Theodosius I, the son of Count Theodosius, a high ranking general under Valentinian I. At the time Theodosius had withdrawn to civilian life in Cauca, Gallaecia after the mysterious execution of his father. Their first son Arcadius, as well as their daughter Pulcheria, were born prior to the elevation of Theodosius as emperor. Their second son Honorius was born on 9 September 384. The Eastern Roman emperor Valens was killed at the Battle of Adrianople on 9 August 378. His nephew and co-emperor Gratian appointed Theodosius, magister militum per Illyricum, to succeed Valens on 19 January 379. At this point Flaccilla became Roman empress and was given the title Augusta. She was a fervent supporter of the Nicene Creed.
