al and statistical reports, literary gerontology provides a framework

ey appear in pairs, force a recognition of the integrating and mediati
ng powers of old women. This paper discusses four Canadian novels in w

hich orders and supports the growth and development of future generati
ons. Through the old women in these novels we may recognize the tradit
ion of the mythic Great Mother in whose image we recognize the full po
wer of our witches, wise women and ordinary old grandmothers.
