In 13th-century England, Franciscan friar Roger Bacon examined the brief reigns of medieval popes—many of whom died within five years of taking office—and concluded that humanity's shortened lifespan was an unmitigated disaster for Christian knowledge. Long before Bacon began his work, ancient thinkers had reached similar conclusions about physical decay. Around the fourth century, Taoist philosophy in China inspired efforts to achieve physical life extension through exercise, diet, herbal medicine, and alchemical potions. Yet Chinese emperors repeatedly died prematurely after drinking immortality elixirs loaded with toxic substances like mercury.
A Franciscan Friar’s Assessment of Human Decay
Born around 1220 in England, Bacon approached the problem of physical decline through a combined theological and alchemical framework. He argued that human lifespan had steadily eroded from the multi-century longevity recorded in the Old Testament down to just 70 or 80 years of toil and physical decay. In Bacon’s view, this decline resulted from centuries of compounding human sin and lost divine knowledge. Bacon was particularly concerned with extending the life of Pope Clement IV, believing that if the pontiff lived long enough, he could successfully unite Christianity.
The Line Between Prolongation and Heresy
Seeking to prolong life was fraught with religious danger in medieval Europe. Claiming to make human beings completely immortal was considered heterodox and blasphemous under Christian doctrine. Absolute immortality belonged strictly to God and could only be achieved after resurrection through Jesus Christ. To suggest that human artifice or alchemy could bypass death entirely was viewed as overriding divine authority. Bacon therefore carefully framed his goal not as eternal life, but as extending human survival for several centuries so scholars could recover lost divine wisdom.
Balancing the Four Elements Like Gold
To achieve physical preservation, Bacon relied on alchemical principles regarding the nature of matter. He believed that gold was entirely incorruptible because it contained a perfect balance of the four elements: air, water, earth, and fire. In ordinary substances and human bodies, one element dominated the others, causing breakdown and physical corruption over time. Bacon reasoned that if an alchemical medicine could balance these four elements within a human body, it would render the physical form far less susceptible to aging and disease.
Starlight and the Inestimable Glory
For his primary remedy, Bacon favored a formulation called the gloria inaestimabilis, derived from the Arabic alchemical text The Secret of Secrets. Preparing the gloria inaestimabilis required fermenting its ingredients for several months and exposing the mixture to beneficial stellar rays before consumption. To defend the feasibility of multi-century life extension, Bacon cited historical legends, including tales of an alchemist named Artephius who had allegedly lived for over 1,000 years.
Roger Bacon died around the age of 80 without seeing any human reach patriarch-like ages, leaving behind a historical record of how ancient and medieval thinkers sought to solve physical decay through the advanced science of their eras. His writings document how early natural philosophers attempted to balance elemental theory, theology, and astronomy into a coherent system for preserving human life.
