Vassago is a mighty Prince of Hell (see Hierarchy of demons), ruling over twenty-six legions of demons. 

He can be persuaded to tell the magician of events past and future, can discover hidden and lost things, and has a “good” nature.

The Third Spirit is a Mighty Prince, being of the same nature as Agares. 

He is called Vassago. This Spirit is of a Good Nature, and his office is to declare things Past and to Come, and to discover all things Hid or Lost. 
And he governeth 26 Legions of Spirits, and this is his Seal.

— Joseph H. Peterson – The Lesser Key of Solomon






4: Marquis Samigina

Gamigin (also Gamygin, Gamigm or Samigina) is a Great Marquis of Hell who rules over thirty legions of demons.

He teaches all liberal sciences and gives an account of the souls of those who died in sin and who drowned in the sea, speaking with a rough voice.

He also answers what is asked about, and stays with the conjurer until he or she is satisfied.

Gamigin is depicted as a little horse or a donkey, which changes form into a man under the conjurer’s request.
