Gaius Pompeius Planta was a Roman eques who was a close associate of the emperor Trajan.
[2] An inscription found at Syene, modern-day Aswan, mentions Planta and a number of other equestrian officers stationed in Egypt, such as praefectus castrorum Lucius Genucius Priscus.
[3] Scholia to Juvenal mentions a history Planta wrote about the Year of Four Emperors, which otherwise is unknown.
He is also mentioned a few times in the collected letters of Pliny the Younger, but not in a manner to suggest they were friends.
[5] Pliny is concerned that now that Planta has died, he should hurry to publication those speeches so to avoid the appearance that he was attacking the man when he could defend himself.
