Cecile may eek be seyd in this manere,
"Wantynge of blyndnesse," for hir grete light
Of sapience and for hire thewes cleere.
– Geoffrey Chaucer
The Canterbury Tales, The Second Nun’s Prologue. The Second Nun says that the name Cecilia may be explained as "lacking in blindness," a shining light of wisdom and pure morals.
