Foras

In demonology Foras is a powerful Great President of Hell, being obeyed by twenty-nine legions of demons. He teaches Logic and Ethics in all their branches, the virtues of all herbs and precious stones, can make a man witty, eloquent, invisible (invincible according to some authors) and to live long, and can discover treasures and recover lost things.

He is depicted as a strong man.

His name seems to derive from Latin 'foras', out, outside.

Other spellings: Forcas, Forras.
