The Odyssey Book 18
Now there came a certain common tramp who used to go begging all
over the city of Ithaca, and was notorious as an incorrigible
glutton and drunkard. This man had no strength nor stay in him, but he
was a great hulking fellow to look at; his real name, the one his
mother gave him, was Arnaeus, but the young men of the place called
him Irus, because he used to run errands for any one who would send
him. As soon as he came he began to insult Ulysses, and to try and
drive him out of his own house.
