I have been going through the set of Goetia Pictures that I recently finished (http://wakingspirals.me/goetia-gallery/) and standardizing the size and style of them. Here is the first set of pictures redone along with a bit about each one from Wikipedia. I am only including the ones that I had to make changes to.:

2)Agares

“Agares (or Agreas), ruling the eastern zone of Hell, and being served by 31 legions of demons. He can make runaways come back and those who stand still run, finding pleasure in teaching immoral expressions. He also has the power to destroy dignities, both temporal and supernatural.
He is depicted as a pale old man riding a crocodile.”

3)Vassago

 

“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”

7)Amon

 

“Aamon is a Marquis of Hell who governs forty infernal legions. He appears as a wolf with a serpent’s tail who can breathe fire, or as a man with a raven’s head, sometimes depicted with canine teeth. He tells of all things past and future. He procures feuds, and reconciles controversies between friends and foes.”

8)Barbatos

 

“Barbatos is an Earl and Duke of Hell, ruling thirty legions of demons and has four kings as his companions to command his legions. He gives the understanding of the voices of the animals, says past and future, conciliates friends and rulers, and he can lead men to hidden treasures that have been hidden by the enchantment of magicians.
His name seems to derive from Latin ‘barbatus’, bearded, old man, philosopher. He is mentioned in The Lesser Key of Solomon.”
