...And ever and anon the wolf would steal
The children and devour, but now and then,
Her own brood lost or dead, lent her fierce teat
To human sucklings; and the children, housed
In her foul den, there at their meat would growl,
And mock their foster-mother on four feet,
Till, straighten'd, they grew up to wolf-like men,
Worse than the wolves...
Lord Tennyson
