“In order to arrive at knowledge of the motions of birds in the air, it is first necessary to acquire knowledge of the winds, which we will prove by the motions of water in itself, and this knowledge will be a step enabling us to arrive at the knowledge of beings that fly between the air and the wind.”

“Quando ouvimos os sinos, ouvimos aquilo que já trazemos em nós mesmos como modelo. Sou da opinião que não se deverá desprezar aquele que olhar atentamente para as manchas da parede, para os carvões sobre a grelha, para as nuvens, ou para a correnteza da água, descobrindo, assim, coisas maravilhosas. O génio do pintor há-de se apossar de todas essas coisas para criar composições diversas: luta de homens e de animais, paisagens, monstros, demónios e outras coisas fantásticas. Tudo, enfim, servirá para engrandecer o artista.”

“As iron rusts when not used, and water gets foul from standing or turns to ice when exposed to cold, so the intellect degenerates without exercise.-Leonard Da Vinci”

“One of Leonardo da Vinci's most famous creations is his painting of The Last Supper. It is said that while Leonardo da Vinci was working on the painting he got into an argument with a fellow painter. Leonardo da Vinci was so mad at this colleague that in anger and out of spite he painted that man's face as the face of Judas in his painting of the upper room Supper.But then, having completed that, Leonardo da Vinci turned to paint the face of Christ and he could not do it. It wouldn't come. He couldn't visualize it. He couldn't paint the face of Christ.He put down his paintbrush and went to find the man from whom he was estranged. He forgave him; they reconciled with one another; they both apologized. They both forgave. That very evening Leonardo da Vinci had a dream and in that dream he saw the face of Christ. He rose quickly from his bed and finished the painting and it became one of his greatest masterpieces.”

“One of the best examples of a polymath is Leonardo da Vinci. Born in Italy in 1452, Leonardo was a sculptor, painter, architect, mathematician, musician, engineer, inventor, anatomist, botanist, geologist, cartographer and writer. Although he received an informal education that included geometry, Latin and mathematics, he was essentially an autodidact, or a self-taught individual.”

“Our life is made by the death of others.”

“The painter has the Universe in his mind and hands.”

“Obstacles cannot crush me. Every obstacle yields to stern resolve. He who is fixed to a star does not change his mind.”

“Don’t say you don’t have enough time or enough money to change the world. You have exactly the same number of hours per day that were given to Helen Keller, Gandhi, Michelangelo, Mother Teresa, Leonardo da Vinci and Jesus Christ.”

“Nothing should be so greatly feared as empty fame.”

“Leonardo Da Vinci combined art and science and aesthetics and engineering, that kind of unity is needed once again.”
