Madrid Exhibition intends to rescue the technique – coloured paint applied to statues – from centuries of indifference

In a darkened corner of the Prado, not far from an outsized crucifixion and a sculpture of a dead, recumbent Christ with eyes of glass, teeth of ivory and fingernails of horn, is another depiction of Jesus that is remarkable in its poignancy, its humanity and its history.

The tiny, painted terracotta scene, titled Los primeros pasos de Jesús (Jesus’s First Steps), is domestic rather than divine and shows a chubby, beaming infant ambling towards his equally beaming father. Its creator was the Spanish baroque artist Luisa Roldán who, despite becoming the first female sculptor to the royal court in 1692, is only now making her debut in the hallowed Madrid museum.
