Severus Alexander Emperor of the Roman Empire from 222 to 235.
Marcus Aurelius Severus Alexander Augustus was Roman Emperor from 222 to 235 and the last emperor of the Severan dynasty.

As emperor, Alexander's peace time reign was prosperous. However, Rome was militarily confronted with the rising Sassanid Empire and growing incursions from the tribes of Germania.

He succeeded his cousin Elagabalus in 222, and was ultimately assassinated himself, marking the epoch event for the Crisis of the Third Century — nearly 50 years of civil wars, foreign invasion, and collapse of the monetary economy, though this last part is now disputed.

A rare left bust coin with none same recorded in acsearch and just one left bust (with shiled) variety recorded in CNG Electronic Auction 181 in 06.02.2008 Lot 238 realized then $260 + buyers fee - and still not the same variety. As noted in the book by Getzel M. Cohen "The Hellenistic Settlements in Syria, the Red Sea, and North Africa", the statue of Kalliope in the fashion of the Tyche of the city being crowned by Seleukos and Antiochos (Malalas 11.276) reappears - with significant modifications - on coins struck by Severus Alexander. On the reverse of the coins we see Tyche of Antioch in the centre; on the left a standing Tyche, holding rudder and cornucopia; on the right a figure in cuirass, crowning the Tyche of Antioch. The latter figure probably a Roman emperor, undoubtedbly Severus Alexander himself, rather than Seleukos.
