In sections on early developments, early imperial reception, and early Christian and late antique Platonism, they consider such topics as Speusippus and Xenocrates on the pursuit and ends of philosophy, Philo of Alexandria, Theon of Smyrna
: rethinking Platonic mathematics in Middle Platonism, variations of receptions of Plato during the Second Sophistic, Plato's political dialogues in the writings of Julian the Emperor, and orthodoxy and allegory: Syrianus' metaphysical hermeneutics.
This date appears to be too late.(4) Apuleius translated the Introductio Arithmetica of Nicomachus into Latin probably at some time in the third quarter of the second century, and there are no references in Nicomachus to Ptolemy or Theon of Smyrna
, who were active mostly in the second quarter of the second century (except for one mention of Ptolemy in the Excerpta ex Nicomacho 4 which may be a gloss by the excerptor).
