Bernard shown holding pillar of flegallation

The picture of St. Bernard shown above is from the title page of the Chronicon Cisterciensis Ordinis (Cologne, 1614). The unusual thing about it is Bernard carrying a pillar. He is often presented with other instruments (nails, sponge, spear) used to torture Christ during the Passion, but rarely is there a pillar. It is, however, established as one of the passion instruments and is venerated as such, as the image below clearly demonstrates.
