Men that look upon my outside, perusing only my condition, and fortunes, do err in my altitude; for I am above Atlas his shoulders.
Another illustration from a book once in the vast library of Sir Thomas Browne Opticorum libri sex philosophis juxta ac mathematicis utiles or 'Six Books of Optics, useful for philosophers and mathematicians alike' by François Aiguilon (1567-1617) a Belgian mathematician, physicist and architect .
Aiguilon's book Optica (1613) was notable for containing the principles of stereographic and orthographic projections, as depicted above. He gave the stereographic projection its current name in his 1613 work. One of the most important uses of stereoscopic projection was in the representation of celestial charts which were increasingly necessary for accurate navigation, exploration and trade-routes, especially for the empire-building of sea-faring nations such as the Dutch and British nations during the 17th century.
Aguilon commissioned the famous Flemish painter Peter Paul Rubens (1577-1640) to illustrate his book. Throughout Aigulion's treatise on optics, Rubens depicts three cherubs who act as guides and tutelary figures to reveal the nature of optical phenomena to the enquirer into Nature's properties.

Just as the study of botany aided the physician in the field of medicine, enhancing his appreciation of the senses through scent and beauty as well as his understanding of nature's organic properties, so too the study of optics held both a scientific and a mystical dimension for the Natural philosopher. The study of optics with its emphasis upon Light and Dark, the visible and invisible worlds and the deceptive nature of appearances has much in common with the spiritual symbolism of Gnosticism and Hermetic philosophy; however symbolism involving Light and Darkness, one of the most richly-developed forms of spiritual imagery can be found in the sacred texts of all world religions, including Christianity. One of the most famous of all optical-spiritual imagery often cited as Gnostic in origin, occurs in the words of Saint Paul -
For now we see but a poor reflection as in a mirror; then we shall see face to face. - 1 Cor. 13 v. 12
