An artistic interpretation of the Visigoths during the Islamic invasion of Spain early in the 8th century. One is a nobleman, who acts as heavy cavalry with sword, shield and spear, the other is a commoner (probably a slave class if I remember correctly) who serves as basic infantry and/or archer. The nobleman's arms and armor is an interesting mix of Roman, Frankish and Byzantine styles.
