Simplicity is the ultimate sophistication.

When once you have tasted flight, you will forever walk the earth with your eyes turned skyward, for there you have been, and there you will always long to return.

Learning never exhausts the mind.

Art is never finished, only abandoned.

Painting is poetry that is seen rather than felt, and poetry is painting that is felt rather than seen.

The human foot is a masterpiece of engineering and a work of art.

It had long since come to my attention that people of accomplishment rarely sat back and let things happen to them.

They went out and happened to things.

I have been impressed with the urgency of doing.

Knowing is not enough; we must apply.

Being willing is not enough; we must do.

As a well-spent day brings happy sleep, so a life well spent brings happy death.

Water is the driving force of all nature.

Leonardo’s Notebooks

Leonardo di ser Piero da Vinci (1452 – 1519) was an Italian polymath of the Renaissance whose areas of interest included invention, drawing, painting, sculpture, architecture, science, music, mathematics, engineering, literature, anatomy, geology, astronomy, botany, paleontology, and cartography.

He has been variously called the father of palaeontology, ichnology, and architecture, and is widely considered one of the greatest painters of all time (despite perhaps only 15 of his paintings having survived).

Although he had no formal academic training, many historians and scholars regard Leonardo as the prime exemplar of the „Universal Genius“ or „Renaissance Man“, an individual of „unquenchable curiosity“ and „feverishly inventive imagination.“

He is widely considered one of the most diversely talented individuals ever to have lived.

According to art historian Helen Gardner, the scope and depth of his interests were without precedent in recorded history, and „his mind and personality seem to us superhuman, while the man himself mysterious and remote.“

Scholars interpret his view of the world as being based in logic, though the empirical methods he used were unorthodox for his time.
