Reduced version of mural painting depicting the astronomical observation of Venus passing across the sun by a draper called Crabtree. The figure is shown in an attic above his shop. He stands to the left, looking up in amazement; his pipe, stool and astronomical equipment lie on the floor, as a shaft of light from his telescope throws a reflection of the planet onto paper propped up on a table on far left. His wife sits on a chair behind him on the right, holding one of her children by the arm; a second child rests against its mother's left arm as she holds knitting in her left hand. In the background, another telescope stands on a large chest covered with drapery in the centre of the room. In the bottom right corner another person is visible through an open trapdoor, ascending a ladder.
