Which event is described in this excerpt from Book 13 of Homer's Odyssey?
She spake, then touch'd him with her powerful wand:
The skin shrunk up, and wither'd at her hand;
A swift old age o'er all his members spread;
A sudden frost was sprinkled on his head;
Nor longer in the heavy eye-ball shined
The glance divine, forth-beaming from the mind.
His robe, which spots indelible besmear,
In rags dishonest flutters with the air:
A stag's torn hide is lapp'd around his reins;
A rugged staff his trembling hand sustains;
And at his side a wretched scrip was hung,
Wide-patch'd, and knotted to a twisted thong.
So looked the chief, so moved: to mortal eyes
Object uncouth! a man of miseries!
