'''Sponsianus''', also known in English as '''Sponsian''', may have been a [[Roman usurper]] during the third century. His existence is implied by a series of coins bearing his name, ostensibly part of a hoard excavated in the eighteenth century. 

No corresponding figure named Sponsianus is mentioned in any ancient sources, and the coins are widely believed to be the work of modern forgers. However, a study of wear marks on the coins published in November 2022 concluded that the coins were authentic, supporting Sponsian's existence as a historical figure. The study's methodology and conclusions have been criticized by a number of scholars.

Scholars who accept the [[historicity]] of Sponsianus date his activity to the [[Crisis of the Third Century]], often locating him in the particularly unstable [[Roman Dacia|province of Dacia]]. More precise dating is a matter of controversy: some scholars have conjectured that he may have proclaimed himself [[Roman emperor|emperor]] in the 260s, after Dacia was cut off from the rest of the [[Roman Empire|Empire]], or in the early 270s after it was formally abandoned by [[Aurelian]]. Others contend he may have been active earlier, during the reign of [[Philip the Arab]] or his son, [[Philip II (Roman emperor)|Philip II]].

== Discussion ==

=== Physical description and provenance ===
The sole evidence for the existence of Sponsianus is his name on a few [[Aureus|double-aurei]] reportedly uncovered in a [[Hoard|coin-hoard]] in [[Transylvania]] in 1713, and subsequently dispersed among several collections.{{NoteTag|The exact provenance of the coins is a subject of controversy among scholars; if the coins are inauthentic, no such hoard could have existed.<ref name="Userpator">{{cite book|title=Verloren Herrscher: Usurpatoren unter den Soldatenkaisern (235–285)|author=Heiko Marenda|publisher=wbg Academic|year=2023|isbn=978-3-534-40749-1|language=German|chapter=4 Sponsianus|pages=50–54}}</ref> (Pearson et al. 2022) catalogues the provenances (as far as they are known) of all the coins said to have been found in the hoard, as well as the provenances of other coins whose distinctive features match those of the coins ascribed to the hoard. There appear to have been seven coins depicting Sponsianus, including a now-lost silver piece. Only four are now extant.}} One was kept in the [[Hunterian Museum]] at [[Glasgow University]], alongside three coins depicting other figures also claimed to have been from the hoard.<ref name=":0">{{Cite news |last=Ghosh |first=Pallab |author-link=Pallab Ghosh |date=24 November 2022 |title=Gold coin proves 'fake' Roman emperor was real |language=en-GB |work=[[BBC News]] |url=https://www.bbc.com/news/science-environment-63636641 |access-date=24 November 2022}}</ref><ref name=":1">{{Cite journal |last1=Pearson |first1=Paul N. |last2=Botticelli |first2=Michela |last3=Ericsson |first3=Jesper |last4=Olender |first4=Jacek |last5=Spruženiece |first5=Liene |date=23 November 2022 |title=Authenticating coins of the 'Roman emperor' Sponsian |journal=[[PLOS One]] |language=en |volume=17 |issue=11 |article-number=e0274285 |doi=10.1371/journal.pone.0274285 |pmid=36417346 |pmc=9683583 |issn=1932-6203 |doi-access=free|bibcode=2022PLoSO..1774285P }}</ref> Another entered the bequest of Baron [[Samuel von Brukenthal]], a Habsburg [[governor of Transylvania]].<ref name=":0" />

The aurei are highly unusual for the period. Firstly, the obverse of the coin features unusual lettering and gives Sponsianus' name in the [[genitive case]] (instead of the usual [[nominative case|nominative]]). Second, the reverse of the coin is a copy of a Republican denarius struck in 135 BC with an apparently corrupted inscription.<ref name="Userpator"/> The coins are also unusually heavy,{{NoteTag|The coins bearing Sponsianus' name and image weigh 10.02 grams on average; for comparison those of Philip said to have been found in the same hoard average 4.30 grams.}} and appear to have been [[casting|cast]], rather than produced using the more usual [[Stamping (metalworking)|stamping process]].<ref name=":5">{{cite book |last1=Pearson |first1=Paul N. |title=The Roman Empire in crisis, 248-260 |date=2022 |publisher=[[Pen and Sword]] |location=Barnsley, England |isbn=978-1-39909-097-1 |url=https://books.google.com/books?id=rylsEAAAQBAJ}}</ref>

=== Traditional numismatic analysis ===
The traditional consensus among numismatists has been to regard the coins as modern forgeries. As early as 1828, [[Joseph Hilarius Eckhel|Eckhel]] noted the strangeness of the coins and concluded against the historicity of Sponsianus.<ref>{{cite book|language=Latin|title=Doctrina Numorum Veterum|author=[[Joseph Hilarius Eckhel]]|volume=VII|edition=2|year=1828|chapter=Sponsianus|pages=340–341|publisher=Sumptibus Iosephi Vincentii Degen |chapter-url=https://books.google.com/books?id=AW4eYPquc2MC&pg=PA340}}</ref> In 1868, the French numismatist [[Henry Cohen (numismatist)|Henri Cohen]] dismissed them as "very poor quality modern forgeries,"<ref name=":0" /><ref>{{cite book |last1=Cohen |first1=Henri |url=https://archive.org/details/bub_gb_adxSECl4cdoC |title=Description historique des Monnaies frappées sous l'Empire romain, communément appelées Médailles impériales |date=1868 |volume=7 supplément |page=254 |publisher=Rollin et Feuardent |author-link=Henri Cohen (composer)}}</ref> and {{ill|Rudolf Münsterberg|lt=Rudolf Münsterberg's|de}} 1923 analysis, concluding that the coins were modern forgeries, is considered definitive by many numismatists.<ref name="y1923">{{cite journal|journal={{ill|Blätter für Münzfreunde|de}}|language=German| volume=58|year=1923|pages=425–428|title=Ein siebenbürgischer Goldmünzenfund aus dem Jahre 1713}}</ref><ref name="RICcrit">{{cite book|title=XII.

Sayles}}</ref> In general, [[ancient history|ancient historians]] have been more willing to accept the historicity of Sponsianus and the authenticity of the coins.<ref name="Userpator"/>

=== 2022 study and reactions ===
In 2022, a group of scientists led by Paul Pearson of [[University College London]] argued that scratch marks on one coin bearing Sponsianus' name and image, visible under an [[electron microscope]], proved that the coin circulated in antiquity.<ref name=":0" /><ref name=":1" /> The group also conducted a chemical analysis, concluding the earth deposits found in the coin's recesses showed that the coins had been buried in soil for hundreds of years.<ref name=":0" /><ref>{{cite book |last1=Pearson |first1=Paul N. |url=https://books.google.com/books?id=rylsEAAAQBAJ |title=The Roman Empire in crisis, 248-260 |date=2022 |publisher=[[Pen and Sword]] |isbn=978-1-39909-097-1 |location=Barnsley, England |page=227}}</ref> The study attracted significant scholarly and media attention, and led the [[Brukenthal Museum]] in [[Sibiu]] to reclassify another coin bearing Sponsianus' image as genuine.<ref name=":0" />

In the aftermath of Pearson's analysis, several researchers have criticized the study and its conclusions. In an article for ''[[The Times Literary Supplement]]'', [[Mary Beard (classicist)|Mary Beard]] suggests that the unusual features of the Sponsianus coin are better explained by its being an eighteenth-century forgery.<ref>{{cite news |last=Beard |first=Mary |author-link=Mary Beard (classicist) |date=2022 |title=When is a Roman emperor not a Roman emperor? |work=[[Times Literary Supplement]] |url=https://www.the-tls.co.uk/articles/when-is-a-roman-emperor-not-an-emperor-sponsian-blog-post-mary-beard/ }}</ref> Richard Abdy,<!--Q42559466--> the curator of the collection of Roman coins at the [[British Museum]], condemned the study, stating "they've gone full fantasy."<ref>{{Cite web |last=Devlin |first=Hannah |author-link=Hannah Devlin |date=23 November 2022 |title=Coins study suggests 'fake emperor' was real, say scientists |url=https://www.theguardian.com/science/2022/nov/23/coins-study-suggests-fake-emperor-sponsian-was-real-say-scientists |access-date=25 November 2022 |website=[[The Guardian]] |language=en}}</ref> In the Journal ''Antigone'', Alfred Deahl argued that the coins are forgeries, drawing attention to the unusual features of the coins as well as the oddness of the other coins purportedly found in the same hoard.<ref>{{cite news |last1=Deahl |first1=Alfred |title=Sponsian: another lost emperor |work=Antigone Journal |url=https://antigonejournal.com/2022/11/sponsian-fake-emperor/ |date=27 November 2022}}</ref>{{NoteTag|{{ill|Carl Gustav Heraeus|de}}, the numismatist who originally received many of the coins purportedly from the Transylvanian hoard, classified a piece bearing the image of Gordian III as a forgery immediately upon receiving the collection in March 1713.<ref name="y1923"/><ref name=":1"/><ref name="Userpator"/> Deahl also notes that eighteenth-century forgers were sophisticated enough to add wear marks to their coins, which they created by placing them in bags with other coins, and handling them to simulate normal usage.}} These doubts are echoed by Aleksander Bursche and [[Kyrylo Myzgin]], who add that the very early finding and low [[gold]] content may count against the coins' authenticity.<ref name=":2">{{cite news |last1=Sharpless |first1=Alice |date=6 December 2022 |title=Is Sponsian real?

Unless further study can provide more certain answers, it seems that these coins should continue to be regarded as modern forgeries."<ref name=":2" />

Pearson's study has attracted significant attention from Romanian numismatists and classicists. Emanuel Petac, President of the Romanian Numismatic Society, stated that the coin "has nothing to do with the Roman world.<ref name=":3">{{cite news |last1=Nicolae |first1=Adrian |title=Monedele cu chipul împăratului roman din Dacia, Sponsianus, un fals ridicol din toate punctele de vedere - opinia specialiștilor |language=ro |trans-title=Coins with the face of the Roman emperor of Dacia, Sponsianus are ridiculously fake from all points of view - opinion of experts |work=[[HotNews]] |url=https://science.hotnews.ro/stiri-interviuri-25926089-monedele-chipul-imparatului-roman-din-dacia-sponsianus-fals-ridicol-din-toate-punctele-vedere.htm |date=25 November 2022}}</ref> Petac notes that the legend irregularly excludes his [[praenomen]] and [[cognomen]], or whose son or grandson he is.{{NoteTag|Son: ''filius'', {{smallcaps|f, fil}}; grandson: ''nepos'', {{smallcaps|n, nep}}.<ref name=":4" />}}<ref name=":4">{{cite news |last1=Vig |first1=Emese |title=Román szakértők a Sponsianus-érméről: az aranypénz hamisítvány, a császár meg nem létezett |language=hu |trans-title=Romanian experts about the Sponsianus coin: the gold coin is fake and the emperor didn't exist |work=Trans[[Telex.hu|telex]] |url=https://transtelex.ro/kultura/2022/11/26/roman-szakertok-a-sponsianus-ermerol-az-aranypenz-hamisitvany-a-csaszar-meg-nem-letezett |date=26 November 2022}}</ref> Another Romanian academic, Florian-Matei Popescu, highlighted the lack of written attestations of Sponsianus or his name—though the name Sponsianus is attested in the Roman world in inscriptions, these are very rare.<ref>{{CIL|6|3959}} ([https://commons.wikimedia.org/wiki/File:CIL_VI_3959_(Le_antichit%C3%A0_Romane,_Piranesi).jpg as originally drawn by Piranesi])</ref> Popescu argues that if the coins are real, which he deems unlikely, they date to the reign of [[Philip the Arab]], who opened a mint in Dacia making low-value bronzes to pay the army.<ref name=":3" />

== The name Sponsianus ==
The name ''Sponsianus'' is an authentic, but exceedingly rare, Roman name, derived from the Latin word ''spondere'', to solemnly promise.<ref>[[Marcus Terentius Varro]], ''De Lingua Latina'' (On the Latin Language), vi. 70 ''ff''.; [[Charlton T. Lewis]] and Charles Short, ''[[A Latin Dictionary]]'', Clarendon Press, Oxford (1879).</ref> Pearson notes only one instance, from a funerary inscription naming an obscure person called Nicodemus Sponsianus, dating from the early first century.<ref>{{CIL|6|3959}}.</ref> This inscription was not published until 1726, several years after the supposed discovery of Sponsian's coins, and Pearson regards this as an argument for their authenticity: a forger would not have known of the name. Two other instances appear in the ''[[Corpus Inscriptionum Latinarum]]'', a catalogue of known Latin inscriptions, all dating from the same period,<ref>{{CIL|6|4188}}, {{CIL|6|5263}}.</ref> while a further two inscriptions give the abbreviated form ''Sposianus'';<ref>{{CIL|6|8901}}, {{CIL|6|26703}}.</ref> all five inscriptions are from Rome. One of the latter was published by [[Jan Gruter]] well before the first known appearance of the coins,<ref>[[Jan Gruter]], ''Inscriptiones Antiquae Totius Orbis Romani'' (Ancient Inscriptions from the Whole Roman World), Heidelberg (1603), p. 581.</ref> and other examples are known besides these, so a forger might still have been aware of or guessed at the existence of such a name.<ref>{{cite book|title=Kenchreai: Eastern Port of Corinth: Results of Investigations by the University of Chicago and Indiana University for The American School of Classics Studies at Athens|volume=V (The Lamps)|author=Hector Williams|publisher=[[Brill Publishers|E.

== Theories ==
Scholars who accept the historicity of Sponsianus have proposed several possibilities for when and where Sponsianus would have been active. One explanation, based upon the other coins found with the aurei, would date Sponsian's activity to the 240s,<ref>{{cite book |last1=Hartmann |first1=Felix |url=https://archive.org/details/herrscherwechsel0000hart |title=Herrscherwechsel und Reichskrise: Untersuchungen zu den Ursachen und Konsequenzen der Herrscherwechsel im Imperium Romanum der Soldatenkaiserzeit (3.

Another explanation is that he was a military commander who crowned himself as emperor when [[Roman Dacia|Dacia]] was cut off from the rest of the empire around 260. With an [[Plague of Cyprian|ongoing pandemic]] and civil war, and the empire being fragmented at the time, Sponsianus may have assumed supreme command to protect the military and civilian population of Dacia until order was restored. The Romans eventually evacuated Dacia between 271 and 275.<ref name=":0" /><ref name=":5" /> According to Jesper Ericsson: 
{{blockquote|
Our interpretation is that he was in charge to maintain control of the military and of the civilian population because they were surrounded and completely cut off. In order to create a functioning economy in the province they decided to mint their own coins.<ref name=":0" />
}}

The [[Roman Empire]] in this period was highly unstable; many peripheral areas were left to fend for themselves. Dacia in particular was abandoned in the 270s by [[Aurelian]] after it was deemed too difficult to defend. Sponsianus may have found himself responsible for thousands of people, without support from the central regime of the empire, and surrounded by hostile tribes; in this context, Sponsianus taking the title of emperor has been characterized as an attempt to maintain order.<ref name=":6">{{cite web |last1=Knapton |first1=Sarah |date=23 November 2022 |title=Long lost Roman emperor revealed as coins give up their secret |url=https://www.telegraph.co.uk/news/2022/11/23/long-lost-roman-emperor-revealed-coins-give-secret/ |website=[[The Daily Telegraph|The Telegraph]] |access-date=24 November 2022}}</ref> He would have had access to a military force consisting of two legions there and their associated auxiliary personnel, totalling tens of thousands of soldiers.<ref>{{Cite news |title=Lost Roman Emperor Long Thought to Be Fake Was Real Leader in Time of Chaos |work=[[Newsweek]] |url=https://www.newsweek.com/roman-emperor-thought-fake-real-leader-sponsian-1761059 |last=Georgiou |first=Aristos |date=2022-12-01}}</ref> No other evidence has been found of Sponsianus' rule, and if he did exist, this would seem to indicate that Sponsianus was either uninterested or unsuccessful in expanding his territory.<ref name=":6" />
