‘Leonardo da Vinci’ Is a Humanizing Look Into a Great Mind

“Leonardo da Vinci,” a four-hour, two-part documentary airing on PBS on Monday and Tuesday at 8 p.m. (check local listings), is a thorough and engrossing biography that can’t help but feel incomplete, so vast and unusual is its subject. “Leonardo, for his time, possesses the most knowledge in the world,” one expert explains.

Narrated by Keith David and directed by Ken Burns, Sarah Burns and David McMahon, this is a straightforward but still lyrical analysis. We learn about Leonardo’s early life, family, education and lovers, and the doc does an admirable job of explaining not just excellence but innovation. Enumerating the areas of his curiosity alone could take four hours, so the focus here is more on his output, whose scope and impact are singular even now. (Though maybe we could revive a few more aspects of his influence: Painting is cool, but why are there so few weddings in which performers dressed as Greek gods bless the union and cavort around a giant gilded half-egg? Something to consider, party planners; Leonardo orchestrated one such event in 1490.)

“For the first time in the history of Western culture, the process becomes the interesting aspect of how art is made,” another expert points out, and “Leonardo da Vinci” follows that path, too.

But beyond the appropriate awe, there’s a through line here of half-starts, dead drafts and lemons — flying machines that can never work, hydroarchitecture that fails completely, paintings never realized for reasons unknown. Those efforts are presented here with an endearing “well, nobody bats a thousand” shrug, adding human texture to the hagiography. One of the greatest minds in human history trails off in one of his final mathematic exegeses because, he writes, “the soup is getting cold.” Geniuses: They’re just like us.
