The Visigoths adopted the Roman monetary system based on a gold unit, the solidus and its third part, the tremissis or triens. The earliest coins faithfully imitated the iconographies of the Romano-Byzantine issues, but there soon emerged a gradual tendency to schematization. After the reign of Leovigild (573-586) a new type was introduced, characterised by the depiction on the obverse of the bust of the king, accompanied by his name and the royal title. On this triens, minted at the mint in 'Hispalis', now Seville, the bust of Sisebut appears on the obverse, seen face on and accompanied by the inscription SISEBVTVS RE. The bust of the king also appears on the reverse, surrounded by the name of the mint and the epithet ‘pious': ISPALI PIVS.
