[1] Kalinke and Mitchell summarise the saga thus: Dámusti is a pious knight at the court of King Katalaktus of Grikkland.
The Virgin Mary appears to the repentant Dámusti, tells him to arm himself and ride to the church where Gratiana lies buried.
There Dámusti defeats the giant Alheimr who reveals that he had induced Gratiana's apparent death in order to marry her himself.
Katalaktus forgives Damusti and the knight marries Gratiana.
When their son is old enough to rule, Damusti and Gratiana turn to the spiritual life and become hermits.
