The events depicted on the Holy Blood Altar are familiar to anyone with a basic grasp of Christian theology of any denomination. The chronological order of the story is read center level from left to right and then from bottom to top: Christ enters Jerusalem, the Last Supper, and the night in the Garden of Gethsemane / Olive Mount. A surprisingly small Crucifixion at the bottom, then a reliquary in the form of a Latin metal cross above the main altar, with a Christ of Sorrows / Mercy at the top.
