Ingrid D. Rowland at The New York Review of Books:
There has never been a painter quite like Jheronimus van Aken, the Flemish master who signed his works as Jheronimus Bosch. His imagination ranged from a place beyond the spheres of Heaven to the uttermost depths of Hell, but for many of his earliest admirers the most striking aspect of his art was what they described as its “truth to nature.” The five hundredth anniversary of his death in 1516 has inspired two comprehensive exhibitions, at the Noordbrabants Museum in his hometown of ’s-Hertogenbosch and at Madrid’s Museo Nacional del Prado, as well as an ambitious project to analyze all of his surviving work, drawn, painted, and printed, according to the latest scientific techniques (the Bosch Research and Conservation Project). Yet despite all we have learned through these undertakings—and it is a great deal—the man his neighbors knew as “Joen the painter” remains as mysterious as ever.
How could it be otherwise with so strange and masterful an artist? His early admirers celebrated the boundless ingenuity of his work, but they also recognized the sureness of his hand and his unerringly observant eye. In the precision of his draftsmanship, his sensitivity to landscape, his fascination with animals, he shows some surprising affinities with his contemporary from Florence, Leonardo da Vinci—who else but Leonardo would have noticed, and recorded, as Bosch does, the way that evening light can turn the waters of a distant river into a radiant mirror? Both artists were fascinated by grotesque human faces, but Bosch also detailed grotesque human behavior with a bawdy abandon all his own. No matter how closely we look at his minutely particular works, there is always something more to see.
