Excellent addition quadrans! An argenteus of Galerius is a wonderful example of Roman proper gander. But beyond that, I believe Galerius is of far greater historical importance than better known emperors such as Caligula. At a time of imperial crisis he and Diocletian defeated the Sassanid Persians, sacking their capital Ctesiphon in 299. He also stabilized the northern frontier, defeating the Carpi in 297 and 300. And although hated by Christian historians for his earlier persecutions, he issued an edict of toleration in 311 helping to set the stage for a Christian empire under Constantine. I wish I had one of his silver coins!
Thank you very much, your nice explanation and comment..
Galerius one of my favourit emperor after Marcus Aurelius and Probus ...
