I’ll be covering the goetic spirit Marbas today; He is known as #5 with description “He answereth truly of things Hidden or Secret. He causeth Diseases and cureth them. Again, he giveth great Wisdom and Knowledge in Mechanical Arts; and can change men
into other shapes”.
Marbas is Saturnian (Capricorn, 21°- experiment) and the only skill that comes remotely close to being a speciality is the ability to give knowledge on mechanics; but in actuality, it is not just that and He can aid in matters of matters where a new idea needs to be developed. Inventors, scientists and people wanting to make a breakthrough in industry & commerce by implementation of new ideas are examples. The other skills mentioned…He can do moderately well at best, but nothing that is worth mentioning.
