Vulcan   and  Maia

Spranger's 'Vulcan and Maia', painted around 1585 and held in the Kunsthistorisches Museum on copper, brings together the lame god of the forge and the elder of the Pleiades nymphs. While Vulcan is more commonly paired with Venus, the pairing with Maia — mother of Mercury by Jupiter — allowed Spranger to explore a less familiar mythological encounter. Copper was a luxury support particularly favored in Rudolfine court painting for its ability to carry highly finished, enamel-like surfaces — the hard, smooth ground allowed extremely fine detail and crisp paint application. Spranger used copper for his most jewel-like compositions, and the intimacy of scale typical of copper supports suited the erotic mythological subjects he produced for Rudolf II's private collections. The emperor collected Spranger's small-format mythological scenes for his Kunstkammer, the celebrated cabinet of curiosities that combined natural specimens, scientific instruments, and works of art in a single space dedicated to universal knowledge. Spranger's mythological copper paintings were among the most prized items in this collection.

The copper support provides an exceptionally smooth ground that amplifies the luminosity of Spranger's paint surface. Thin, transparent glazes in the flesh areas achieve a depth impossible on canvas, while the small scale demands — and rewards — close inspection. Spranger's brushwork becomes even more controlled on copper, with fine details rendered in minute strokes.
