It's no secret that certain reaches of Tumblr have a reputation for being collections of softcore porn, mostly in the form of modern artworks, n00dz and pure commercial smut, however most users are unfamiliar with the grandfather of racy porno drawings: one much-loved Heinrich Lossow. But that's probably because dude's been dead for over a hundred years.

Granted, the 19th century German artist's most well-cited work is a retroactively painted picture of Marie Antoinette and he's known mainly as a Rococo-inspired artist, like at a time when all that gold, froofy excess was pretty outdated. So poor Heinrich obviously was a pretty, uh, imaginative fellow stifled by the constraints of Neoclassicism and Romanticism -- a fact proven by his pretty whatever day-job paintings as a genre painter:

So what's a guy to do? Well, take up pornography as a side job, obviously.

So let's start with his most famous/complete porntastic painting -- a work called "The Sin" which depicts a moment of fornication from The Ballet of Chestnuts, a legendary orgy hosted in the Vatican by a cardinal whose dad just happened to be the Pope. Talk about one of the biggest "You're Grounded!" moments in Western history, amirite?

However, Heinrich's portfolio goes way deeper, with a ton of drawings featuring face-sitting, dick forests, Satan and more -- aka Tumblr Gold. Can you say new favorite ye olde artist? Peep a few more of his racy side sketches below -- and remember, it's all NSFW ;)
