The Vitruvian Platypus

Finally, after countless years of research! Above is the definitive study of the proportions of the male Platypus, faithfully sketched as described in a treatise by the ancient Roman architect Platruvious Maximus, around the year 18 BC.

Note that the center of the circle lies above the heart of the creature, symbolizing its spiritual existence. The center of the square, on the other hand, lies above its belly; symbolizing its material existence. Furthermore, note that 3 and 1/4 lengths of the bill is equal to the creature's length. The latter measurement is also equal to 13 lengths of the fore-claw; and also note that 5 widths of its tail is equal to a cubit. So you see, it all makes sense.

Yes, who would have known that the anatomy of the average ornithorhynchus anatinus, otherwise known as the platyus, serves as a cosmography of the microcosm! In other words, an analogy for the workings of the entire universe. Yes, it is self-evident that our universe is analogous to a venomous, egg-laying, duck-billed mammal.

O noble platypii, rejoice in the knowledge that your divinely proportionate form serves as a beacon of light and reason in these dark times!
