Celestial Alphabet

The Celestial Alphabet, also known as Angelic Script, is a set of characters described by Heinrich Cornelius Agrippa in the 16th century. It is not to be confused with John Dee and Edward Kelley's Enochian alphabet, which is also sometimes called the Celestial alphabet. Other alphabets with a similar origin are Transitus Fluvii and Malachim.

Origin
The language was first made by scholars studying angelic kingdoms, specifically Heinrich Cornelius Agrippa in the 16th century. The script was first published in his third book Of Occult Philosophy. The script and language was invented in order to communicate with angels and it was later claimed that these symbols were sent "by God", given to angels, and then passed along to humans. No known major books have come out written in this script.

Nowadays, it is still occasionally used in rituals.

Style
There are 22 known characters, most of which are based around Hebrew names, such as Gimel, Sameth, and Aleph. It is an abjad, meaning there are no vowels. It is read and written from left to right in horizontal lines.
