The Magus, or Celestial Intelligencer

THE Hebrew characters have marks of numbers attributed to them far more excellent than any other language, since the greatest mysteries lie in the Hebrew letters, as is handled concerning these in that part of Cabala which we call Notariacon. Now the principal Hebrew letters are in number twenty-two, whereof five have various other certain figures in the end of a word, which, therefore, they call the five ending letters, which, being added to them aforesaid, make twenty-seven; which being then divided into three degrees, signify units, which are in the first degree--tens, which are in the second--and hundreds, which are in the third degree. Now every one, if they are marked with a great character, signifies so many thousands, as here--

The classes of the Hebrew numbers are these which follow:--

Sometimes the final letters are not used, but we write thus:

And by those simple figures, and by the joining them together, they describe all other compound numbers: as eleven, twelve, an hundred and ten, an hundred and eleven, by adding to the number ten those which are units; and in the like manner to the rest, after their manner; yet we describe the fifteenth number not by ten and five, but by nine and six, viz. וט and that out of honour to the Divine name יה, which signifies fifteen, lest that sacred name should be abused to profane things. Likewise the Egyptians, Æthiopians, Chaldeans, and Arabians, have their marks of numbers, which serve for the making of magical characters; but the Chaldeans mark their numbers with the letters of their alphabet, after the manner of the Hebrews. I found, in a very antient book of Magic, some very elegant characters, which I have figured in the following manner

Now of these characters, turned towards the left hand, are made tens.

And those marks being downwards, to the right hand, make hundreds; to the left, thousands, viz.

And by the composition and mixture of these characters, other compound numbers are most elegantly made, as you may perceive by these few:--
