The Arras Medallion was issued to commemorate Constantius Chlorus' recovery of Britain and the rescue of London in 296 AD It is the intention of this critical source to evaluate the medallion and determine its value for the study of government and society under Diocletian. The source provides valuable information on what the tetrarchs looked like. It will be suggested that the source reveals the tetrarchs' promotion of images portraying them as united and equal. Furthermore there is a sense of militarism and just government that the Tetrarchs also wished to promote. Together with the confirmation of the literary sources and a possible, however slight, example of individualism, they make the sources valuable with regards to tetrarchy propaganda. The legend deciphered on the obverse of the coin (Flavio Valerio Costanzo noble Caesar) identifies the figure as Costanzo Cloro. The inclusion of the PTA on the bottom of the reverse indicates that it was made in Trier. Given that it is identified as Caesar, the coin can be attributed to a period between 293 and 305 AD However, as the reverse shows a depiction of the reconquest of Britain, it was probably commissioned in 296/7 AD. Constantius is seen wearing a laurel wreath and armor and looking to the side. These features, along with the stubble, are key similarities shared by many Tetrarchic coins. In fact the coins of the tetrarchs are so similar in shape that without the legend identification of the individual would be difficult. This was part of the tetrarchs' desire to appear united and equal to provide contrast to the destructive divisions that occurred in the early 3rd century. According to Southern, the adoption of Flavius ​​Valerius into his name was also... in the middle of the paper... an example of the tetrarchic unity being questioned. The source also corroborates the literary account and reveals the tetrarchs' desire to appear righteous to power. Whether the source is an accurate representation of the reaction to the tetrarchs is another question entirely. Overall, the Arras medallion proves valuable in the study of Diocletian's reign as it provides information on how the tetrarchs wanted to be perceived.
