"I have offended God and mankind because my work didn't reach the quality it should have"

This quote by Leonardo da Vinci talks to the artist's humility and self-awareness. He acknowledges that his work has actually not reached the quality it need to have, and in doing so, he has actually upset both God and mankind. This recommends that Leonardo da Vinci held himself to a high requirement, and was dissatisfied when he failed to satisfy it. He knew the significance of his work, and the impact it had on others. This quote also speaks with the artist's dedication to his craft. He wanted to take responsibility for his errors and strive to do better in the future. This quote is a testament to Leonardo da Vinci's commitment to excellence and his respect for the divine. It is a pointer that even the best of artists can make mistakes, which it is very important to gain from them and pursue improvement.
