Is there anything left to learn about Leonardo da Vinci? The Italian Renaissance master, who has been dead for 500 years, is one of the most celebrated and studied figures in human history. And rightfully so, given an undeniable genius that moved humanity forward with breakthroughs in medicine, mathematics, engineering, art and numerous other fields. The outlines of da Vinci’s accomplishments are clear from miles away, etched as they have been into global popular culture, from flying machines to the Mona Lisa to the first detailed human anatomical drawings. But there’s reason to take a closer look. “This exhibit really focuses on every aspect of his creative genius,” said Samantha Sands, museum program specialist and lead educator for the Leonardo exhibition at the Denver Museum of Nature & Science.
