Animals, plants, rocks, and bones rendered (literally) down to the micrometer, rich in detail… Do you remember how fascinating they seemed to you when you leafed through encyclopedias as a child? You learned from them what all those leaves, tracks, butterfly wings, and bird feathers—or even aquarium fish—looked like.
It probably never occurred to you back then that someone had spent hours and hours constructing those almost photographic miniature works. He studied, tested colors, meticulously searched for textures, and sought out the most precise spectra to transform 3D into 2D. They seem so natural that we don’t even realize the virtuosity with which they were created. Acrylic, ink, watercolor, graphite… he worked with many techniques.
Ján Švec’s son Andrej describes his father’s creative process: “He created most of the illustrations on a 1:1 scale relative to the original model. Imagine, for example, a butterfly—the hairs on its body or its antennae are a tenth of a millimeter long, and my father was able to paint them that thin. But that meant he sat over the picture for hours and often worked on it under a magnifying glass.”
His output of scientific illustrations for children is enormous: Our Birds, From the Realm of Insects, The Aquarium in a Nutshell. Many of them are still passed from library to library today. They’re often pulled out just for a moment—when children and parents enjoy figuring out together what they actually saw in the forest, examining the tiny differences. Or placing tracing paper over the pictures and starting to trace them. Following the author’s style precisely, layering the pencil sketch, filling it in with aniline dyes, and even outlining it with ink.
These illustrations are so natural that we don’t even realize their virtuosity. They actually came about by chance. Some titles from the Mladé letá publishing house had square formats, but they were cut from rectangular sheets, resulting in waste measuring roughly 10.5 centimeters by 15 centimeters. However, the publishing house did not want to waste anything and considered how to make use of it. Someone came up with the idea that these scraps could serve as the basis for small atlases with highly precise, almost scientific illustrations.
1930, Bánovce nad Bebravou – 2017, Bratislava. Jan Švec studied at the Faculty of Education of the Slovak University under Gustáv Mallý, Bedrich Hoffstädter, and Eugen Nevan. Almost immediately after graduation, in 1956, he joined the publishing house Mladé letá as an art editor and remained there until 1991. Over the course of decades, he edited and designed dozens of books. He specialized in illustrating educational literature, such as the books *From the Realm of Insects* (1964), *Aquarium in a Nutshell* (1968, 1973, 1982), Our Beetles (1973), Our Birds (Vol. 1: Songbirds, Woodpeckers, and Others, 1963; Vol. 2: Birds of Prey, Owls, Grouse, and Others, 1964), Our Butterflies (1977), as well as Coats of Arms of Our Towns (1970) and Guild Emblems (1975). He also designed postage stamps. His free-form work remains little known—powerful pieces full of optical illusions composed of clear shapes, influenced by Constructivism.
