The solidus (the
Latinword for "solid") was originally a gold coinissued by the Romans.
The solidus was first introduced by
Diocletianaround 301, struck at 60 to the Roman poundof pure gold (c. 5.3g) and with an initial value equal to 1000 "denarii". ["The Cambridge Ancient History", p. 335, by Alan K. Bowman, Peter Garnsey, Averil Cameron. http://books.google.com.sg/books?id=MNSyT_PuYVMC&pg=PA343&lpg=PA343&dq=diocletian+solidus&source=web&ots=uJv5fVNl4T&sig=F4fByBoS91YsSbsTQ-OKGeuZijc&hl=en&sa=X&oi=book_result&resnum=4&ct=result#PPA335,M1] However, Diocletian's solidus was only struck in small quanities, and thus had only minimal economic impact.
The solidus was re-introduced by Constantine I in
312, permanently replacing the aureusas the imperial gold coin of the Roman Empire. The solidus was struck at a rate of 72 from a Roman poundof pure gold, each coin weighing twenty-four Roman/Greek caratsPorteous 1969] , or about 4.5 grams of gold per coin. By this time, the solidus was worth 275,000 increasingly debased denarii.
The solidus maintained essentially unaltered in weight and purity until the
10th century, though in the Greek-speaking world during the Roman period and then in the Byzantine economyit was known as the "nomisma" (plural "nomismata"). Porteous 1969] Whenever the coin was taken in by the treasury, it was melted down and reissued. This maintained the evenness of the weight of the circulating solidi, since the coin did not tend to be in circulation for long enough to become worn.Porteous 1969]
Minting of the gold coin - unlike the base-metal coins of the time - had no permanently established minting facility. Due to the requirement that taxes were paid in gold, solidus minting operations tended to follow the emperor and his court. For example, solidi were minted in
Milanin 353, and in Ravennaafter 402. Each of these locations were imperial residences at those times.Porteous 1969]
Although merchants were forbidden from using solidi outside of the Byzantine empire, there was sufficient trade in these coins outside of the empire that they became a desirable circulating currency in Arabic countries. Since the solidi circulating outside the empire were not used to pay the taxes to the emperor they did not get re-minted, and the soft pure gold coins quickly became worn.Porteous 1969]
Through the end of the 7th century, Arabic copies of solidii - dinars minted by the caliph
Abd al-Malikwho had access to supplies of gold from the upper Nile- began to circulate in areas outside of the Byzantine empire. These corresponded in weight to only 20 carats, but matched with the weight of the worn solidi that were circulating in those areas at the time. The two coins circulated together in these areas for a time.Porteous 1969]
Except in special cases, the solidus was not marked with any face value throughout its seven-century manufacture and circulationFact|date=July 2008. Solidi were wider and thinner than the
AureusFact|date=July 2008, with the exception of some lower quality issues from the Byzantine EmpireFact|date=July 2008. Fractions of the solidus known as "semissis" (half-solidi) and "tremissis" (one-third solidi) were also producedFact|date=July 2008.
The word "soldier" is ultimately derived from "solidus", referring to the solidi with which soldiers were paidFact|date=July 2008.
Impact on world currencies
In medieval Europe, when the only coin in circulation was the silver penny (denarius), the 'solidus' was used as a unit of account equal to 12 denarii. Variations on the word "solidus" in the local language gave rise to a number of currency units:
To this day, "sou" is used as slang a small coin of little value, as in "sans le sou". "I'm broke", "without money". It is also a slang term for the Canadian cent (standard French, "cent").
The name of the medieval Italian "soldo" (plural "soldi") was derived from "solidus".This word is still in common use today in Italy in its plural "soldi" with the same meaning as the English equivalent "money".
pain and Peru
The name of the medieval Spanish "sueldo" (which also means salary) was derived from "solidus", which is also used in the Philippines as "Suweldo". Subsequently the name of the
Peruvian "sol" (more formally "sol de oro" intended to mean "gold solidus") was derived from this name although, because "sol" actually means "sun" in Spanish (from the Latin"sol"), the etymologyof the currency's name is commonly misunderstood. To complicate matters, the Sun God was a foremost figure of the Incan Empirethat reigned in what is now Peru.
Until decimalisation in the
United Kingdomin 1971, the abbreviation "s.", from "solidus", was used to represent shillings, just as "d." and £, from " denarius" and "Libra", were respectively used to represent penceand pounds, leading to the abbreviation " £sd".
