There are plenty of websites that display artwork by Hieronymous Bosch (Bosco, age 26, in "Contagion Collectors") and Albrecht Durer (Dire, age 4, in "Contagion Collectors"). Wikipedia, for example, has plenty by both. In order to save you a search, I've highlighted a few of them.

In terms of Bosch, I took the Juggler and the lower edge of the front cover for Contagion from a triptych entitled 'The Garden of Earthly Delights'. For reasons made clear therein, it's called the garden of earthy delights in Contagion. The mini-novel also makes clear that Bosch didn't make it up — at least he didn't within the phantacea Mythos.

'The Ascent of the Empyrean', which appears on both the front and back cover of Contagion, is one-fourth of a major work entitled 'Visions of Beyond'. The version I used is from a poster replacing the actual painting in the Doge's palace of Venice. Apparently the original was being cleaned while I was there in 2008.

As for Durer, the putto (who once ate Sinistral Envy), Drang (not yet a dachshund, thus not yet having wolfed down the murine crud containing Camorva Freeflight) and Herta Heartthrob (a technically daemonic, hence soulless, earthborn eidolon given flesh) come from Melancholia.

(Should perhaps add, as a bonus teaser, that Herta is a melancholic angel in the sense that she has wings and is lovely, except she seems plagued by sadness at her own lack of fulfillment. Above all else, she wants to wholly devour the Unity of Balance, whom even she perceives as Beauty Incarnate, instead of simply settling for gathered-up scum-cream left behind on Tholoi hearthstones that Harmony used to get to the Outer Earth in pursuit of Tomcat Tattletail – a character introduced as such in Hellion – long, and often, pre-book.)

Both Death and the goatish Devil came from 'The Knight'. The 'Four Horsemen' came from just that. As for why he depicted the rider with the Scales of Justice (unless it's for weighing produce in times of pestilence, drought, and/or consequential famine) as a man instead of the most incomparably gorgeous woman ever beheld by everyone, well, assuming the phantacea Mythos isn't pure fantasy, Dire was only 4 at the time of Contagion and might have been missing his mother, if not his dog.

The British Museum has piles of Durer's prints. It even puts out a small hardcover that can probably be ordered online as if just to prove it. I scanned in the ones I used for the covers on this page, as well as its background images, from art books I already had at home.

Just by the bye, as per here, Durer's Death looks a lot like old King Cold, Tantal Thanatos, did in the comic books. Which is doubly appropriate since Cold is one of the aforementioned Death Gods of Lathakra – the other being immediate sister Methandra, Hot Stuff, Mithras's Virgin (in both Feel Theo and Hellion, though no longer in the comic books) or just plain Heat (after her attribute) – and Thanatos is the name of the Ancient Greek God of Death.

Just as interesting (to me anyhow), Durer's Devil might well be someone the recurring deviant, Pusan Wanderlust, would fall for in both Hellion and Contagion. That's because, as per here, Pusan's a female faun or fauna and everyone knows what fauns are best at doing, a lot. It's also why I incorporated Durer's Devil into the Deviancies graphic.

NOTE: the last two images in this panel don't double-click. They roll over, rather effectively I feel.
