But, Blake has chosen to represent the instrument of death as an actual tree. In this way he makes nature an integral part of this event. This is consistent with the romantics' use of nature as messenger, not mere backdrop. The tree is large enough to be a major player in this portrait, yet is too dark to be distracting. It possesses no detail.
Nature is also present in one of the light sources.
It lies on the otherwise invisible horizon line. This is one of only two sources from which light emanates, the most prominent being the head of Jesus. It shines on his neck, upper arms, chest and then down onto the face on Albion. There is even brightness from Christ to illumine the upturned face of Albion. The light is clear, sharp, and direct.
