The Celestial Alphabet, also known as Angelic Script, is a set of characters described by Heinrich Cornelius Agrippa in the 16th century.

Other alphabets with a similar origin are Transitus Fluvii and Malachim.

The language was first made by scholars studying angelic kingdoms, specifically Heinrich Cornelius Agrippa in the 16th century.

[1] The script was first published in his third book Of Occult Philosophy.

[1] There are 22 known characters, most of which are based around Hebrew names, such as Gimel, Sameth, and Aleph.
