Homer was right

Soon in the luscious feast themselves they lost,
And drank oblivion of their native coast.
Instant her circling wand the goddess waves,
To hogs transforms them, and the sty receives.
No more was seen the human form divine;
Head, face, and members, bristle into swine:
Still curs’d with sense, their minds remain alone,
And their own voice affrights them when they groan.
Meanwhile the goddess in disdain bestows
The mast and acorn, brutal food! and strows
The fruits and cornel, as their feast, around;
Now prone and grovelling on unsavoury ground.
