thanks everyone, and thanks for posting all those cool plautillas! looking at martins caracalla/plautilla pair, i didn't really consider that caracalla was just a young teen as well when they were married.
Plautilla's father was an old friend of Septimius and was making every effort to set himself up as second in command or even heir apparent to Septimius after Albinus had been replaced with the young Caracalla (born 188, he was ~8 when he became Augustus). Had Septimius died in 196-203, I suspect Caracalla would have met with and 'accident' and Plautian would have become emperor probably over the dead bodies of Domna and a pile of others. As Caracalla grew older and more self assertive, Plautian was killed, it is said, by agents of the 15 y.o. Caracalla who never wanted to marry Plautilla in the first place. There were many personalities in Rome over the centuries but Caracalla would be hard to top when it comes to pure cussedness. He was not a playboy, a religious fanatic or stupid. He was decisive and in charge. In the business he was in, perhaps those were not bad characteristics. We like to think Geta would have been better but that is one we will never know.
Coin is cool - but the photo is straight up amazing. How far you have come. I do miss the table though.
