Who dated Gala Placidia?

Élia Gala Placidia (en latín: Aelia Galla Placidia; Constantinopla, entre 388 y 393-Roma, 27 de noviembre de 450) fue la hija del emperador romano Teodosio I y de su segunda esposa Gala, emperatriz consorte de Constancio III, emperador del Imperio Romano de Occidente y madre de Valentiniano III, emperador de Occidente. Gala era media hermana de los emperadores Honorio y Arcadio.

Eucherius was the son of Stilicho, the magister militum of the Western Roman Empire, and Serena, a Roman noblewoman who was the niece of Eastern Roman Emperor Theodosius I. He was born in c. 388 in Rome, Italy. Despite being the son of the magister militum, Eucherius did not rise farther than the modest rank of tribune of the notaries. Stilicho was accused by his political opponents of plotting to install Eucherius as a third emperor in Illyricum, and as a result of this Stilicho was arrested and executed on 22 August 408, and Eucherius soon after.
