This font makes use of the most ancient forms of each of our capital English letters. Glyphs that would have been repeated because of shared origins have been given alternate forms of the original glyph to enable differentiation. The question and exclamation mark originate with Latin, written with two letters vertically, and in this version are written the same way but with the original forms of the letters. The rest of the punctuation comes from Greek origins or is made to look similar. The following website can act as a key for the meaning of each letter: http://www.ancient-hebrew.org/3_al.html
