the association of wisdom and virtue in Plato's _Phaedo_, the myth of Er in the _Republic_, and the doctrine of love and beauty in the _Symposium_.
[93] See Plato's _Symposium_.

According to Mary's note in her edition of Shelley's _Essays, Letters from Abroad, etc_.

(1840), Shelley planned to use the name for the instructress of the Stranger in his unfinished prose tale, _The Coliseum_, which was written before _Mathilda_, in the winter of 1818-1819.

Probably at this same time Mary was writing an unfinished (and unpublished) tale about Valerius, an ancient Roman brought back to life in modern Rome.

Valerius, like Shelley's Stranger, was instructed by a woman whom he met in the Coliseum.
