Take a step back to 18th-century natural history with the remarkable illustration named Squalus Centrina from Marcus Elieser Bloch, who is known for his regional names for the illustration, namely Das Meerschwein, La Centrine, and The Centrina. This remarkable copperplate engraving created by the master artist for his book called Ichthyologie, ou Histoire naturelle, générale et particulière des poissons (1782-1795) represents the characteristic triangular body shape, dorsal fins, and skin texture of this fascinating underwater creature. This work of art is a brilliant example of combining the principles of science and the aesthetics of the Enlightenment era.
