Theodor Kittelsen was a Norwegian painter and book illustrator (1857-1914). He illustrated the Scandinavian bestiary of legend and fairy tales, and his work has scared countless children (myself included). He drew and painted trolls, the black death, sea monsters, nøkken ("water spirit"), and anthropomorphised natural phenomena such as the echo. His work can be rather ...

Auguste Racinet was a French illustrator, famous for his detailed depictions of historical costumes. His polychromatic ornaments are also a thing to marvel, just take a look at these five motives from Persia, Byzantine, Medieval, Renaissance and 18th Century style: His masterpiece, however, remains to be Le Costume Historique, an unprecendented attempt to illustrate the entire history ...

In the chaos that is self-employed life, it's hard to find the time to do personal projects. Personal work is a great way to explore styles and hone your skills. Especially as a graphic designer, I think personal work is muy importante. But when do I do it? After about a year of not doing ...

There is a fairy tale here in Norway, called the twelve wild ducks. The story is not really important, it a fairly classic good versus evil, patience, purity and deceit. I think it is a pretty convoluted story, and I always found it dissatisfying that there is no attempt at explaining why the princes are ...

Scientific illustrations by Carim Nahaboo Carim Nahaboo is a London based illustrator specialising in accurate depictions of natural history subjects as well as more imaginative, conceptual themes. So says his bio on his webpage, and who am I to argue? I am in awe of his work; this is old-school scientific illustration: art, design and ...

Saul Bass is the genius behind movie legends such as The Shining, The Man with the Golden Arm, Vertigo and Anatomy of a Murder. During his 40-year career Bass worked for some of Hollywood's most prominent filmmakers, including Alfred Hitchcock, Stanley Kubrick and Martin Scorsese. It was his work for The Man with the Golden Arm that made ...

Kjell Aukrust was a legendary artist, humourist and illustrator. He is most famous for his wacky stories from a particular part of rural Norway, full of bizarre and hilarious people, inventions and creatures. They make little sense to people from other countries, the Danes certainly do not get it at all. I grew up with ...

Audubon's birds have been released to Public Domain! John James Audubon's book Birds of America is usually listed among the rarest books in existence. The reason for this is that the French ornithologist used the laborious technique of hand-coloured etched and aquatint plates, which means that there only about 200 complete sets done. A set fetched £7.3m at auction ...

They say in art the greatest compliment is to be copied, and the greatest compliment for poster design is when your poster gets stolen. It seems that print posters are dying. Now we have digital screens that cycle – for the most part – commercials. Should we care? Are posters merely something arty people and ...

Maria Sibylla Merian (1647 – 1717) was a remarkable woman in many ways. She was a very talented scientific illustrator and had a passion for insects. According to David Attenborough, she contributed immensely to taxonomy in entomology and the understanding of metamorphosis, and she was the first person who travelled on purely scientific grounds. Though ...

Here at the visual squirrels, we are not in the habit of promoting stuff, but Calamityware is simply too funny. Taking the classic language of cobalt and porcelain decoration, the artist Don Moyer adds – well – calamity. Volcanoes, robots, tentacles, and all manner of funny creatures hide in the china. The only problem with ...

I made this infographic to show the (current state of things for) human evolution. Or quite current, because there have been some new discoveries, but they are still being debated. Feel free to download, distribute and change it, but please don't crop my name off it as it took me a long time to make it! Licence ...

Prime numbers are a cryptographer's dream: It's easy to take two very large prime numbers and multiply them, but it's extremely hard to do the opposite. There is no fast algorithm (yet) to factorize an integer into its prime factors, if you try to factor a large prime number you'll have to try every possible number between 2 ...

A long time ago I made a geologic timeline as a (vector) brush in Illustrator, with .ai and .eps files free for anyone to use. The only thing I ask is that if you use it, let me see the result. Making the timeline was incredibly time-consuming and ludicrously fiddly. So, a while ago I got ...

I write this blog together with Yisela (and Vincent). I have never met either, but Yisela was such a dear that I figured she deserved a gift. So in the tradition of Sofie's book and Adam's book, I made Yisela's book. But you have to be supersupernice to me to get one; well over and ...

In a lot of medieval manuscripts, there are depictions of knights fighting snails. No one seems to know why this is. There are some theories, but so far nothing really conclusive. It might look like some sort of insider thing, maybe among scribes or illuminators. I love that sort of thing: mysteries in plain sight ...

I can't talk about inspirational art for very long until I brush the subject of Magic: the Gathering. I've been playing this geekery-heavy card game for almost twenty years now. In that period, a humonguous amount of fantasy art has been produced by a myriad of artists. It was this art that drew me to ...

...and perfection is not a detail. I am a great fan of the work of Amanita design and their games, in particular, Machinarium. Because of this enthusiasm, I have been told that my drawings are heavily influenced by Machinarium and Samorost. But here is the thing; I loved that sort of humour, aesthetics, whimsy and ...

“Listen to the mustn'ts, child. Listen to the don'ts. Listen to the shouldn'ts, the impossibles, the won'ts. Listen to the never haves, then listen close to me... Anything can happen, child. Anything can be.” I only discovered Shel Silverstein a few years ago... I can only blame it on not having grown up in an ...

Thore Hansen was one of my childhood heroes. His drawings were magic then, and they are still magic now. The best known of his children's books illustrations are the ones accompanying Thor Åge Bringsværd's stories about Ruffen. Ruffen is a "small" sea dragon, and the books tells the story of his adventures. This post was ...

Many moons ago, when a friend of mine acquired his first nephew, he wanted to give him a story. We co-wrote the story in google docs, and I was to do the illustrations. I forgot all about it, until the day before I was due to fly to the US (and the deadline for producing ...

I posted about stylisation before, and I'd like to show where I got my inspiration. So without further ado, some of the 'plates' from J.H. Boot's book on how to take some natural object and turn it into something of mathematically precise art. It still amazes me that Boot did not just take the time ...

Since we are on a roll with old books and manuscripts, I give you the 240-page Voynich manuscript. It is an unsolved enigma: a manuscript found in Italy; the paper has been dated to between 1404-1438. It contains text in an unknown script, unknown language, and illustrations of non-existing plants, constellations and humans apparently doing ...

Back in the mist of time, I did my apprenticeship in hand bookbinding. There are basically two directions; two different apprenticeships: literature binder, or ledger binder. I am a literature binder (also called publishing or library binding). But back then it was considered essential to have a broad understanding. So part of the apprenticeship was ...

Yisela The Upper Paleolithic or Late Stone Age begins and ends with a revolution. The first one is what can be considered the 'official' appearance of art, some 50,000 years ago. The second, the invention of agriculture, 40,000 years later. The earliest sample of Paleolithic art is the shells with holes and chipped edge modifications from Ksar Akil. These flakes show regular teeth distributed ...

I have a thing about drawing skulls and bones. Not of any morbid fascination (I think), but because they can really be a challenge. The texture and colour of bones are interesting, and the ultimate challenge is to draw a skull first with graphite on white paper, then with white pencil on black paper. This ...

Beatriz Aurora calls her drawings "painted stories", and her subjects definitely have a lot to tell. The Chilean artist had to exile to Spain during the 70s. She knew she couldn't go back to Chile, but there were other places in Latin America that could use her art, so from Spain she travelled to Nicaragua, then to El Salvador and finally ...

Both my father and his father have been interested in art and decoration. Apparently, things like those are in the blood. Recently, my father passed me along scans of a book by one J.H. Boot he found in his archives, which must have belonged to my grandfather. It's a book about stylisation, the art of ...

For the geo-geeks out there, I have finished my geologic timescale brush; now better and more accurate than the previous one. Download the Illustrator file here Download .EPS file here Included is a swatch folder with all the colours as per the instructions of the International Commission on Stratigraphy: You are welcome to use this in ...

William Buelow Gould (1801 – 1853) was an English artist convicted for stealing a coat and was sentenced to seven years of labour in Van Diemen's Land (Tasmania). He constantly got into trouble, also in the penal colonies, and was regularly punished for offences such as drunkenness, petty theft and forgery. His talent, however, got ...

During an extended period of the depression in USA (between 1935-1942), the US federal government supported artists by commissioning artwork for non-federal places and activities. Early on in the project, posters were painted by hand, each individually created. Later on, they were printed with silk screen. According to the US library of congress, "over two ...

Yisela Utopias. The no-places. I’ve always been attracted by them. The first utopia ever written could have been Plato’s Republic. Or the Genesis. However, the first one I discovered was Thomas More’s Utopia. I still can’t believe it was written 498 years ago, in 1516. Utopia is a strange book. Most scholars agree it’s a satire, a criticism ...

(I was horrified to discover that Wikipedia does not have an entry on Fritz Kahn in English. I was utterly unaware of how deep into obscurity this multitalented man had fallen. Update: my pigheaded ability to pester strangers have resulted in an solid entry on Kahn on Wikipedia. Many thanks to Yngvadottir ). man as ...

Giorgia Lupi once again comes up with stunning, informative and elegant data visualisation. This time, the life cycle of ideas. You can see another of hers in my post Design is where science and art breaks even ...

Q. Why was longitude boiling mad? A. Because it was 360 degrees. Cartographers are/were often seen as pretty dour characters. Not so long ago, maps were hand-drawn, and hanging over a drawing table, the meticulous of drawing contours seems rather nerdy. But, as programmers put easter-eggs in code, cartographers do the same. Map makers sometimes ...

Frank Jacobs blog about weird maps is a source of laughs and curiosity. It contains the real, the fictional, the fantastic and the self-made. He found a map of USA with each state named after a country with corresponding GDP, though I would have liked a colour-coded intensity added, it is well worth a study. (I ...

You can actually buy some stuff with my drawings on them. Here, some examples of the human skull drawing. Head over to my CafePress home and have a look around (considering posters. Maybe later.). glass framed tile woven pillow card pendant t-shirt magnets sigg bottle coffee mug ...

Ernst Haeckel Ernst Haeckel (1834 – 1919) was what we call a renaissance man. He was a professor, biologist, philosopher, physician, naturalist and artist. His contribution to biology, evolutionary theory and art is still mind-boggling; we owe a great deal of biological understanding and terminology to him. He was a great promoter of Darwin's theory ...

The sphere is, according to Wikipedia, a reasonably correct model for earth. But mathematically the earth is  an oblate spheroid. An example of that would be smarties and M&Ms, spheres squished at the poles. As a result of gravitation and the rotation of earth, it is about 21 km longer than the Earth’s polar radius. This is, of course, ...

In 1854 there was a cholera epidemic in London. The accepted theory at the time was that illness and epidemics spread through the "miasma", a form of "bad air", pollution and smell emanating from decomposing organic matter. The mechanics of germs was not understood. Dr. John Snow was sceptical to the miasma theory, but not entirely grasping germ mechanics, ...
