A marble bust possibly representing Valens or Honorius
Valens (/ˈveɪlənz/; Latin: Flavius Julius Valens Augustus;[2] Greek: Οὐάλης; 328 – 9 August 378) was Eastern Roman Emperor from 364 to 378. He was given the eastern half of the empire by his brother Valentinian I after the latter's accession to the throne. Valens was defeated and killed in the Battle of Adrianople, which marked the beginning of the collapse of the Western Roman Empire.
