Hello!
I am really glad that "The Birth of Venus" by Botticelli was used to underline the existence of this tribe. In his representation of "Spring", 500 among flowers and plants are painted, go figure. This incredible fact was discovered years ago as this marvellous painting was restorated. This is the product of high skills combined to a wonderful sensitiveness in depicting details. Botticelli was more a spiritual and a perfect Reinassance artist as to his research on beauty perfection in his paintings.
Leonardo Da Vinci (known for his "Gioconda") was a complete Renaissance member. Renaissance was an era in which artists, literates, and scientists got freedom to research new perspectives in a way free from the chains of belief. The man was in the middle of the universe, free to discover past cultures, assimilate and melt them in their current age. Arts were already experiencing a qualitative development especially in sculpture in the early XIV century. Sculpture was not only a mere figurative art per se, aimed to represent the magnificence of god. It was experiencing a more human characteristic. I quote Donatello who gave the pulse to research human fears, pain, frailty, power and joy in all his works. He started Renaissance in sculpture, definitely. He started investigating on humanity. As for painting, all Leonardo Da Vinci's works are detached from being pure spirit. The real man is at the centre of all. This was, at last, the aim that arts had always to pursue: Real knowledge. Real awareness. Real effort to teach the others that there is a mankind and nature living on earth, not only religion, not only crowns to bless as such. Saints and nobles painted by Leonardo are human, at last. Closer to follow, if their magnificence had to be taught to people.
