The Fourth Pentacle of the Sun
This serveth to enable thee to see the Spirits when they appear invisible unto those who invoke them; because, when thou hast uncovered it, they will immediately appear visible.
The Key of Solomon is the best known of the Renaissance grimoires, surviving in dozens of manuscripts in Latin, French, Italian and Hebrew. Mathers made his 1889 edition from seven manuscripts in the British Museum, and it is his plates that every later reproduction of these pentacles descends from.
The Key of Solomon the King (Clavicula Salomonis), translated and edited by S. Liddell MacGregor Mathers (London: George Redway, 1889). The text and the pentacles are in the public domain.
The pentacle is traced from the plate in the De Laurence edition of 1914 (Chicago: De Laurence, Scott & Co.), which reprints Mathers' plates at a larger size, and checked line for line against the 1889 printing.
Mathers' note: The Names IHVH, Adonai, are written in the centre in Hebrew; and round the radii in the mystical characters of the “ Passing of the River.” The versicle is from Psalm xiii. 3, 4:—“ Lighten mine eyes that I sleep not in death, lest mine enemy say, I have prevailed against him.”
