How was the Beaune Altarpiece or The Last Judgement painted

Response:
The Beaune Altarpiece (or The Last Judgement) is a large polyptych c. 1445–1450 altarpiece by the Early Netherlandish artist Rogier van der Weyden, painted in oil on oak panels with parts later transferred to canvas. It consists of fifteen paintings on nine panels, of which six are painted on both sides. Unusually for the period, it retains some of its original frames.

Six of the outer panels (or shutters) have hinges for folding; when closed the exterior view of saints and donors is visible. The inner panels contain scenes from the Last Judgement arranged across two registers. The large central panel spans both registers and shows Christ seated on a rainbow in judgement, while below him, the Archangel Michael holds scales to weigh souls. The lower register panels form a continuous landscape, with the panel on the far proper right showing the gates of Heaven, while the entrance to Hell is on the far proper left. Between these, the dead rise from their graves, and are depicted moving from the central panel to their final destinations after receiving judgement.
