23 Deluge
A sonic punctuation by Gruppen (Brennan, Brannagan & Riccardi)

23 Deluge is a collaborative sonic work by Gruppen, featuring Sara Riccardi, and formed as a ritual response to Leonardo da Vinci’s apocalyptic mirror-text: “Of the deluge and how to represent it in a picture” (1517–18).

The work will be published in early 2026 within Performing Punctuation, edited by J. Preston and A. Brown (Intellect Books), and will be made available in audio form via Intellect’s digital platform.
23 Deluge is a textual reconstitution: translation, distortion, and coding converged into a final form rendered in International Morse Code—a language of distress, command, obfuscation, and colonial transmission.

Da Vinci’s original mirror-written fragment is treated not as historical text but as prophetic transmission—a kind of 16th-century S.O.S.
Gruppen’s process involved:
– Translating da Vinci’s mirror-script via multiple human and machine vectors
– Rewriting and revoicing the material through morse code
– Rendering the code as punctuated soundwork—a sonic inscription
The final artefact evokes both ritual and resistance—an encrypted deluge, a fractured broadcast.
