The Haywain Triptych

The Haywain Triptych is a panel painting by Hieronymus Bosch, now in the Museo del Prado, Madrid, Spain. A date of around 1516 has been established by means of dendrochronological research. The central panel, signed "Jheronimus Bosch", measures 135 cm × 200 cm (53 in × 79 in) and the wings measure 147 cm × 66 cm (58 in × 26 in). The outside shutters feature a version of Bosch's The Wayfarer.

History The painting was part of a group of six acquired by King Philip II of Spain in 1570, and shipped to El Escorial four years later. It was later sold to the Marquis of Salamanca, and divided into three paintings. In 1848, the central panel was bought by Isabella II of Spain and brought to Aranjuez, the right one was returned to Escorial and the left went to the Prado. The triptych was finally recomposed in 1914 in the latter museum. A copy exists at the Escorial.

Painting materials The triptych was thoroughly investigated by the scientists at the Bosch Research and Conservation Project with the results published in book form. Bosch's palette was rather limited with pigments including azurite, lead-tin yellow, vermilion and ochres.
