In "The Children's Hour," how is the children's attack similar to the attack on the Bishop of Bingen, and from what source is the allusion drawn?

The attack of Alice, Allegra, and Edith upon Longfellow
have more differences from than similarities to the attack upon the Bishop Hatto of
Bingen of Longfellow's literary allusion. The girls' attack is one of love as they
"devour [him] with kisses" and as he reciprocates by putting them "down in the dungeon /

Folk Tales from Many Lands retold by Lillian Gask, with
illustrations by Willy Pogany.

Bishop Hatto is attacked by the spirits
of murdered town folk who possess the bodies of rats to take revenge upon the Bishop.
The darkly shaded (making this allusion an odd one for Longfellow to choose for his
playful poem--except that it may have been a familiar nursery folk tale) similarities
between the attacks are these. The children descend in a "sudden rush" and "sudden raid"
to take their hapless victim by "surprise" as do the rats in their descent upon the
Bishop. Both children and rats breach the "castle wall." Both swarm "everywhere" and
