The article linked by Paul is curious ......
The (senior) Emperor is repeatedly referenced as Septimus Severus and mentioned as being different by virtue of having had facial hair (with the exclusion of M Aurelius). By my own count (Commodus, Pertinax, Didius Julianus,Pescennius Niger and Clodius Albinus) every single Emperor between Marcus and Septimius had whiskers ! For over 70 years if you count Marcus as Caesar and follow through to Caracalla every 'emperor' who was old enough to have a beard grew one. Only ending with Elagabalus and we know about him don't we .....
Then the writer states that Septimius "exited power" AD 198 apparently not realizing that Septimius and Caracalla were joint rulers for the next 13 years ?
Lastly is the mention that Geta died in "his brothers arms" ? Obviously he/she means in his mothers arms but it is rather a glaring error.
Interesting family portrait by the way. Just rather surprising that so many errors could be included in so short an article ! I would hope that the author was not a History Major ...... nor that they had spent more than a few minutes composing and researching it !
