Title says it all. I've been slowly expanding my Diocletian series and late Roman coins from the post-crisis period into the Tetrarchy. Diocletian's rise, as is true of many others, is one filled with military exploits and dramatic intrigue. Afer Emperor Carus was struck by lightening after defeating the Sassanids; Diocletian secured his power by personally killing Aper the alleged murderer of Numerian who was Carus' son and a short-lived emperor with his brother Carinus. That story is very dramatic in itself. Wow, it is easy to digress when talking ancient Rome. The Rise of Diocletianus | Weapons and Warfare Diocletian likely gained power through his contribution to the very successful military campaign of Carus as the commander of the elite calvary of the emperor. His political power came through fortune and opportunity or through clever planning depending on the sources and through our +1,700 year lens. An interesting thing I've come across are these pre-reform radiate / antoninianus from Tripolis: Diocletian 284-305 A.D. Antoninianus RIC V-2 330 Victory 284? Tripolis radiate, draped, cuirassed bust right IMP CC VAL DIOCLETIANVS PF AVG / IOVI CONSERVATORI AVG Victory walking right, holding palm, presenting wreath to emperor who is standing left holding globe and sceptre. TR in lower centre, XXI in exergue 22mm 4.16g I've seen these with Jupiter and a small victory in place of the larger crowning victory. Looking at Augustus Coins Tripolis mint, Roman Empire (augustuscoins.com) I believe it is RIC V 330 with the single G, i.e. prior to Maximian, in the obverse putting it at sometime before 286 but I'm not sure why Wildwinds would have 284 as the mint date. Doug Smith also has a page on the XXI mark here: XXI (forumancientcoins.com) Supposedly this coin was minted in 284 just as Diocletian ascended and prior to removing Carinus in 285. It does appear Triopolis was an active mint under Carinus but it's curious that so many coins could have been minted there and it does appear they were produced quickly to recognize Diocletian. Presumably Tripolis had important military functions as well as trade at this time. I didn't do a very good job of cleaning the coin prior to photographing it as it looks like fibers are stuck to it pretty good and my standard of using air didn't cut it. I'm wondering if this patina is fake or just been absorbing stuff over the years. Carinus RIC V-2 325 284 Antioch Diocletian RIC V.2 220 Ticinum 285 The other radiates I have come from the 290's, with at least one Diocletian additional I can't find at the moment that I'll post as a follow-up: Galerius RIC VI 16 Delta Heraclea 295-296 Constantius RIC 40b (RIC 41?) Votive Ticinum 299 Curious to see what you guys have from Tripolis, these radiate types or Diocletian.
