It is a sad fate for a man to die
Too well known to everybody else,
And still unknown to himself.

[Illi mors gravis incubate
Qui notus nimis omnibus
Ignotus moritur sibi.]

Seneca the Younger (c. 4 BC-AD 65) Roman statesman, philosopher, playwright [Lucius Annaeus Seneca]

Thyestes, ll. 401-403 [tr. Bacon]
