An Imperial medium beard and a Provincial short one from Marcianopolis (a Pentassarion with facing busts of Macrinus and Diadumenian):
A beautiful Macrinus you have there @Shea19 A recent non-lovely Macrinus led me to a comment on his beard, found in Henry Jewell Bassett's University of Michigan dissertation "Macrinus and Diadumenianus" (1920). Here is what he says: "Authorities agree the new emperor spent the winter in luxury and effeminacy to the neglect of administrative affairs. His dress was elaborate and his personal adornments were better fitted to a barbarian court than to the provinicial headquarters of a Roman emperor. He imitated Marcus Aurelius in slowness of gait, in speaking in a hesitating manner and in a low tone, and even in the method of trimming his beard..." (p. 49) The chapter before this section, Bassett discusses Macrinus-Diadumenian's coinage, his theory being that the huge provincial issues for Moesia, etc. were in response to the new emperor's travels through these areas. This is available on Google Books here: https://books.google.com/books?id=POA7AQAAIAAJ&pg=PA46&dq=marcianopolis+and+macrinus&hl=en&newbks=1&newbks_redir=0&sa=X&ved=2ahUKEwjq093M4ujzAhUhMn0KHSWFCGMQ6AF6BAgJEAI#v=onepage&q=marcianopolis and macrinus&f=true A more recent comment on the beard of Macrinus can be found in Caracalla: A Military Biography by Ilkka Syvänne. Syvänne claims the soldiers were actually angered by Macrinus's longer beard, since it was a break with Caracalla's short beard: "The bearded Macrinus imitating Marcus Aurelius signified a break with Caracalla's coins and medallions. It is no wonder that when the soldiers got their first bearded versions of Macrinus that they started to feel anger building up..." The page quoted here, with line drawings of the coins, can be found here (but for some reason this book seems to lack page numbers - it is towards the end of the book): https://books.google.com/books?id=RtLLDwAAQBAJ&pg=PT498&dq=macrinus+aurelius+beard&hl=en&newbks=1&newbks_redir=0&sa=X&ved=2ahUKEwievuTstuzzAhUFrJ4KHZDEDUUQ6AF6BAgHEAI#v=onepage&q=macrinus aurelius beard&f=false I was looking into Macrinus because I got a low-grade provincial off eBay recently - any Macrinus under ten bucks seems like a bargain to me, but I've been wrong about "bargains" before.
