Malachim Alphabet

In his book Of Occult Philosophy, Henri-Corneille Agrippa de Nettesheim describes an alphabet (a script) called Malachim, a name derived from a Hebrew word, meaning angel.

The Malachim writing/script is presented on page 440 of Book III, dated from the 16th century and here is a scan:

Malachim writing is a transcription of Hebrew characters into a Malachim symbol.

NB: There are 23 symbols for 22 letters of the Hebrew alphabet, the character Samech has 2 glyphs.

To encode from the usual Latin alphabet, a transliteration is necessary.

The decryption of the Malachim alphabet is a substitution of the Malachim symbols by their Hebrew letter equivalent. To read in the Latin alphabet, a transliteration is required, however, not all Hebrew characters have a Latin alphabet match (such as ט or צ), and some Hebrew letters have multiple equivalents in the alphabet (like ג for C or G, ו for F, V or U, or even י for I or J).

Malachim symbols are mainly made up of several straight (but sometimes curved) lines accompanied by circles (or large circular dots) at their ends.

For some, the symbols look like constellations.

All references to occult or esoteric sciences, magic, angels, or to Henri-Corneille Agrippa are clues.

The Celestial alphabets or the Passing of the River alphabet are very similar.

Malachim was published in the 16th century, it could be an invention of the author of the book Heinrich Cornelius Agrippa.
