The Twelvefold Brain – Alesha Sivartha (c. 1898)

The Twelvefold Brain is drawn from The Book of Life (1898) by Alesha Sivartha, presenting the mind as a structured system organized around the number twelve.

The diagram divides cognition into ordered regions, using numbered sections and precise linework to articulate a formal architecture of thought rather than an expressive image. In this IkonHaus edition, the original illustration has been carefully restored and cleared of its aged background, allowing the structural logic of the diagram to emerge with contemporary clarity.
