This piece is named for Leonardo da Vinci (1452- 1519), a painter, sculptor, architect, musician, engineer, geometer, inventor, and scientist from the Renaissance period. Although he is the most famous for his artistic masterpieces, Leonardo da Vinci was also one of the greatest scientific minds ever to have graced the earth. Writing on everything from optics to hydraulics, Leonardo da Vinci also performed extensive studies on human anatomy and used his artistic mastery to depict the first elaborate, detailed studies of the human body, the skeletal and muscles, organs and reproductive system.

Visionary, herbalist, healer, scientist, poet and composer, Hildegard of Bingen was one of the greatest women of the 12th century. The famous abbess was is considered by many the mother of the gregorian chant with dozens of beautiful compositions to her credit -- many which have been revitalized for a popular audience. More than 300 years before Kepler, Hildegarde depicted the elliptical shape of the planetary orbits. Matthew Fox has said, "If Hildegard had been a man, she would be well known as one of the greatest artists and intellectuals the world has ever seen."

Pappus of Alexandria(c. 290 – c. 350 AD) was one of the last great Greek mathematicians of Antiquity, known for his Synagoge or Collection (c. 340), and for Pappus's Theorem in orijective geometry. Nothing is known of his life, except (from his own writings) that he had a son named Hermodorus, and was a teacher in Alexandria.Collection, his best-known work, is a compendium of mathematics in eight volumes, the bulk of which survives. It covers a wide range of topics, including geometry, recreational mathematics, doubling the cube, polygons and polyhedra. (from Wikipedia)

Marcus Vitruvius Pollio (born c. 80–70 BC, died after c. 15 BC), commonly known as Vitruvius, was a author, architect, and civil engineer during the 1st century BC, known for his multi-volume work entitled De Architectura. By his own description Vitruvius served as an artilleryman, the third class of arms in the military offices. He probably served as a senior officer of artillery in charge of doctores ballistarum (artillery experts) and libratores who actually operated the machines. Vitruvius gives us the famous story about Archimedes and his detection of adulterated gold in a royal crown. When Archimedes realised that the volume of the crown could be measured exactly by the displacement created in a bath of water, he ran into the street with the cry of Eureka!, and the discovery enabled him to compare the density of the crown with pure gold. He showed that the crown had been alloyed with silver, and the king defrauded. (from Wikipedia)

The Pythagorean school was as much a Sisterhood as a Brotherhood. Theano of Crotona (6th Century BCE) was a philosopher, physician, astronomer and mathematician. Along with her three daughters, she was a student of Pythagoras and was one of the most celebrated of the Pythagoreans. Theano later married Pythagoras and directed his school after he died with her sons, Arimnestes and Telauges. Although Pythagoras did not write his own teachings down, Theano was known through her many written works on cosmology, virtue and mathematics. Theano’s most important treatise was on the principle of the Golden Mean. Theano is a member of the Spheres of Pythagorus at PORCELAINia.com

Ancius Manlius Severinus Boethius was a Roman statesman, philosopher and Christian theologist from the 6th century. His translations reviving earlier Greek writings led him to be considered the Medieval Father of the Seven Liberal Arts and his image was depicted in medieval manuscripts next to Pythagoras. Boethius’ writings on arithmetic, geometry and music drew from Pythagorean traditions, kept alive before him in the cosmology of Plato’s Timaeus, Cicero’s Somnium Scipionis, and Nichomachus’ Arithmetica. After Boethius died, his writings became the most influential and widely read works of the medieval period. Boethius is a member of the Spheres of Pythagorus at PORCELAINia.com
