What is "charmadas"

Charmadas (; or Charmides ; 168/7 – 103/91 BC) was an Academic philosopher and a disciple of Carneades at the Academy in Athens. He was a pupil of Carneades for seven years (145-138) and later he led his own school in the Ptolemaion, a gymnasium in Athens. He seems to have spent some time in Alexandria, before he went to Athens around 145 B.C. He was an excellent rhetorician and famous for his outstanding memory. Like Philo of Larissa he seems to have pursued a more moderate scepticism. Lucius Licinius Crassus and Marcus Antonius (orator) were his most prominent pupils. Furthermore, Philodemus preserverd us the names of other pupils: Diodorus of Adramyttion, Apollodor of Tarsus, Heliodorus of Mallos, Phanostratus of Tralles and a certain Apollonius.
