Dr Richer was a French sculptor and anatomist. He penned two incredible human anatomy books: Artistic Anatomy with a focus on skeletal and muscular forms, and Female Morphology with a focus on the female figure and deciphering the bodies variations.
His sculpture Tres in Una is the result of these incredible studies of anatomy and morphology. The female figures are depicted in 3 styles- that of Antique, Renaissance, and Modern.
The postures, the objects they are depicted with, and they manner in which their body is rendered are shown to typify the ideal types of sculptures from each period.
An amazing work to see in person, it is located in Paris, France.
