Leonardo di Ser Piero da Vinci was an Italian polymath who lived during the Renaissance, and one of the finest mind of human history.
At the beginning of the 16th Century, the ageless sex-swapping adventurer Orlando met Leonardo and agreed to pose for his portrait called The Monna Lisa. While Leonardo portrayed Orlando as woman, he didn't know that the immortal was changing into a man at the time. Leonardo frequently asked Orlando why he was smirking.
After his death, Leonardo ascended into a another realm of existence, becoming part of a group of science-mystics alongside Pytaghoras, Galileo, Archimedes and Aristotles. During the 1950's, the quintet granted their power to Jim Logan, a British operative of the United Nations, who became the super-hero Captain Universe.
