If you’re not familiar with the website Retronaut  (and you really should be), it’s a collection of all manner of vintage photographs and illustrations spanning millenia. One can easily spend vast amounts of time perusing this site!

The site recently featured a number of beautiful colored engravings on scientific topics by John Philipps Emslie, a Victorian age illustrator.  I find his work beautiful and strangely modern in the methods he uses to impart information. Reproduced above is his Diagram of Meteorology.  Retronaut has a couple of collections of his work.
