Leonardo’s notebooks are filled with illustrations of nature, both plants and animals, their interactions with humans and in local ecosystems. Did his deep engagement with the natural world make him an environmentalist ahead of his time?
Leonardo was a child of the Tuscan countryside, raised in the tiny village of Anchiano, although he spent most of his adult life at the courts of dukes, kings and princes.
Some of his work for these patrons involved planning interventions into nature, most often managing waterways, but his sketches suggest his attention roamed further than the projects he was commissioned to undertake.
He spent time with friends in a villa outside of Milan observing the country nearby and sketching plans for gardens there, and ended his life on a little country estate that was then on the outskirts of Amboise in France.
One of his first biographers, Giorgio Vasari, tells us that Leonardo
Leonardo was also reportedly a vegetarian. This supposition comes from the explorer Andrea Corsali’s description of the non-meat-eating Gujarati people (from modern India) as like “our Leonardo da Vinci”.
The many notebooks and loose sheets Leonardo filled with jottings and illustrations across his lifetime reveal his close observation of nature — from cats and crabs to flowers and copses of trees - and the spirit of enquiry from which he drew many lessons.
One jotting simply states: “Ask the wife of Biagio Crivelli how the capon nurtures and hatches the eggs of the hen”.
His understandings of the habits of animals informed a series of fables and proverbs bearing witness to various emotional traits he attributed to them: gratitude, rage, cruelty and generosity among them. He suggested, for instance, that “we see the most striking example of humility” in the lamb.
The random cruelty of nature
But Leonardo was also struck by the violence of natural processes. Nature appears to have been “rather a cruel stepmother”, he wrote. “Why did nature not ordain that one animal should not live by the death of another?”
He reflected on the random cruelty of nature in a series of riddles, created across his notebooks. For instance, in the entry on walnut trees, he writes in emotional terms of the violence wrought upon these trees as humans enjoyed their seeds: “beaten, and their offspring taken and flayed or peeled, and their bones broken or crushed.”
Still, Leonardo does not seem to have been particularly concerned about the role of humans in enacting violence against other species. His own quest for knowledge and artistic creativity demanded it.
Vasari tells a story of the young Leonardo seeking to depict a frightening creature on a shield he had “brought for this purpose to his room, which no one entered but himself, lizards, grasshoppers, serpents, butterflies, locusts, bats, and other strange animals of the kind …” “The smell in the room of these dead animals was very bad, though Leonardo did not feel it from the love he bore to art.”
Vasari talks of how Leonardo “suffered much in doing it” - but not as much as the other species whose lives were sacrificed for his art.
In other tales, Vasari tells us how Leonardo, while he was working for Giuliano de’ Medici in Rome, discovered an unusual lizard and promptly
For Vasari, these stories show Leonardo’s “marvelous and divine” mind, but they could also be interpreted as showing the instrumental way in which Leonardo thought about nature, as a resource to expand human knowledge and control the environment.
His contemporaries clearly thought there was something different about Leonardo and his interest in nature. Does this make him a kind of pre-modern environmentalist?
Western environmentalism (and before it, preservationism) is often understood to have become possible when nature had been subdued by technology. With urbanisation and development of a middle class, more people could feel sentimental about nature.
Although he was raised in the countryside, Leonardo spent most of his everyday adult life in major European towns in the company of princes and kings. He was no longer concerned directly with the need to cut down wood for warmth or kill animals for food. We could say, then, that he could afford to be more sentimental about nature.
Certainly his exquisite drawings suggest a particular depth of feeling, attunement and sensitivity to the natural world. And yet it seems that preservation of nature was not on Leonardo’s mind.

He had not witnessed the speed and scale of devastation of the natural world wrought by humanity with the onset of industrialisation. Instead, he understood destruction as part of the cycle of nature. If, as he wrote, nature “seeks to lose its life, desiring only continual reproduction”, there was nothing to be protected, for annihilation and creation went hand in hand.
