About Tabula
The name
Tabula means three things at once, and all three are the product:
- A plate. Anatomical illustrations are tabulae, and every discovery here is a numbered plate: Tab. I to Tab. XXVI.
- A blank slate, the tabula rasa. The body begins as unwritten paper and is inked in over 3,600 years.
- Vesalius's first anatomy, the Tabulae anatomicae sex of 1538: six broadsheets with pictures keyed to captions. That is what this site is, five centuries on.
About the fog
The timeline asks a deliberately modern question: how much of today's anatomy was known in a given year? That is a measure of the past against the present, and we say so plainly. Past physicians had complete, coherent models of their own. You can see those models in red ink (beliefs of the time) and in the Traditions lens.
The rules for what is drawn are simple and public:
- Blank paper (a faint contour only): no story in our set has described this part yet.
- Outline: described. The part was seen and recorded, including at microscopic scale, but what it does was not yet understood.
- Hatching and colour: understood. Its function, or its working at molecular level, was explained.
- Red ink: a belief held at the time. It fades when first challenged and is scraped away when the mainstream gives it up.
- Organs visible to the naked eye that have no story yet (the liver, stomach or spine, say) are shown in outline throughout. Today is the modern reference, so everything is fully inked.
- Plates marked Revised correct a popular myth. They never ink anything in.
The order in which knowledge arrived is uneven, and that is the point.
The art
Knowledge is shown as ink because that is how the history was made: in manuscripts, woodcuts and copperplates. The figure here is Tabula's own schematic engraving, drawn as a stand-in for a commissioned engraving. The paper behind it changes with the era, from papyrus to vellum to laid rag paper to modern stock.
