Caspiel is the Chiefest Emperor Ruling the South who hath 200 great Dukes & 400 lesser Dukes under him besides 1,000,200,000,000 of Ministring Spirits which are much inferior & whereof we [saith Solomon] shall make no mention but only of these 12 being the chief Dukes & their seals for they are sufficient for practise. Each of these 12 Dukes have 2660 under Dukes apeace to Attend them, whereof some of them come along with him when he is invocated but they are very stubborn & churlish.
