Agrippa's celestial script: letters drawn from the stars

Looking at the night sky and seeing words written in it is an idea as old as astrology. In the Renaissance this intuition took the form of a real alphabet: the celestial script, which Heinrich Cornelius Agrippa published in the third book of the De occulta philosophia, printed in its complete form in Cologne in 1533. Its letters are made of small circles joined by thin lines, just like the figures astronomers traced between the stars.

Twenty-two Hebrew letters among points of light

The skeleton of the celestial script is the Hebrew alphabet. Each letter corresponds to one of the twenty-two Hebrew letters, from aleph to tav, and keeps their order and value. What changes is the drawing: the strokes become segments, and at their ends small rounds appear that represent the heavenly bodies. The result recalls the celestial maps of the period, where constellations were rendered with dots and lines.

Agrippa places this alphabet beside two other scripts derived from Hebrew, Malachim and Passing the River. In his view the three forms belong to a tradition of sacred scripts used by the ancient Hebrew sages and handed down by the Kabbalists. This is a learned reconstruction and not a documented history: no ancient evidence of these alphabets is known.

The sky as a book

At the root of the celestial script lies an idea that runs through Jewish and Christian culture: that God wrote in the firmament, and that whoever knows how to read can decipher that writing. Medieval Kabbalists spoke of letters as creative forces, and the Sefer Yetzirah, the Book of Formation, associated them with stars, planets and zodiac signs. In the Renaissance these suggestions merged with learned astrology and with the taste for symbols.

A century after Agrippa, the Frenchman Jacques Gaffarel devoted a chapter of his Curiositez inouyes, published in 1629, precisely to the writing of the stars. Gaffarel reproduced maps of the sky in which the constellations were read as Hebrew letters, and claimed that future events could be glimpsed in them. The work was condemned by the Sorbonne and the author had to retract, but the theme continued to circulate.

Use and fortune

In the treatises that followed Agrippa, the celestial script was used above all to write divine and angelic names on talismans, seals and pentacles. Its form, made of circles and lines, lent itself well to engraving on metal and to copying in manuscripts. In later centuries it was taken up by many authors on occultism, often without any indication of its Renaissance origin.

It should be remembered that Agrippa himself, in his later years, distanced himself from magic in the treatise De incertitudine et vanitate scientiarum, published in 1530, in which he criticised many branches of learning, the occult art included. This did not prevent the De occulta philosophia from continuing to be read as a manual, nor its sacred scripts, the celestial one among them, from being copied into the notebooks of countless readers all over Europe.

The celestial script is a rare example of an alphabet born from an image of the world. It did not serve to communicate between people, but to recall that, according to a long tradition, the sky itself was a text to be interpreted. In those small circles joined by lines we see the reflection of an age in which astronomy, theology and Hebrew philology still spoke to one another on the same page.
