(urth) the voice of the outsider is the conjunction of pas/kypris

[Lee Berman]

Just had to add something which occurred to me and may sound crazy or may have
occurred to others. The means by which Wolfe suggests the motherhood of Catherine 
and Mamelta are similar, requiring a non-logical intuition. In one case Severian is 
staring a a pool  of clear water in the woods and her face "tears at his heart", etc. 
In the other, Silk is disconcertedly staring at the crotch of a woman for whom the very 
sound of her name invokes motherhood.
 
For me there is just a lot of similarity there though it's hard to say exactly why.
