Starz has renewed “Da Vinci’s Demons” for a second season, based on the performance of its first episode.

Sunday’s premiere drew 1.04 million viewers, and clocked more than 2 million over the weekend. That’s Starz’s highest-rated premiere weekend ever.

Tom Riley stars in the “historical fantasy” about the “untold story” of the polymath during his “turbulent youth in Renaissance Florence.” Lucky for Starz, little is actually known about Leonardo’s youth, giving the network a lot of room to get historically fantastic. This made-for-TV Leonardo, for instance, is a swarthy heterosexual studmuffin.

Starz describes Leonardo as “brilliant and passionate, an artist, inventor, swordsman, lover, dreamer and idealist.” Leonardo also was known to be no slouch at math, engineering, geology, cartography and botany, but expect that to be hushed up on the series, for the sake of ratings.

“I’m excited that we get to continue the adventures of the world’s most eccentric and glorious polymath. Long live Leonardo and thanks to Starz for helping to make it happen,” series creator David S. Goyer (“The Dark Knight”) said in Wednesday’s news.
