The daughter of Kyrina and Diogenes, Theodora was, like
Iamblichus, descended from royal line of
Emesa. The Athenian neoplatonic school had developed a following among Syrian and Egyptian pagan students at the turn of the fifth century, and Theodora, along with her younger sisters, had studied philosophy at the school of Isidore in Alexandria. This could have been in the 480s when Isidore was already well established within the intellectual Alexandrian milieu, or in the 490s after his return from Athens. She was also accomplished at poetics and grammar, a mathematician versed in geometry and higher arithmetic. She was a neoplatonist of the Iamblichean type, so a devout
pagan. According to
Photius, writing three centuries later, she performed pagan rites and
theurgical operations: he describes her as a ‘Hellene by religious persuasion,’ and her ancestors as ‘all of them first prize winners in idolatrous impropriety.’ Damascius's
Life of Isidore illustrates the ease with which the philosophical circle to which Theodora belonged moved in the late fifth and early sixth centuries between Athens, Alexandria and Aphrodisias. There is no record of Theodora fleeing to Persia after
Justinian’s order to close the Platonic school in Athens in 529, along with Isidore, Damascius, Simplicius, Priscianus Lydus,
Eulamius of Phrygia, Hermias the Phoenician, and Diogenes the Phoenician. ==The
