An old man (the astronomer) and a young man (his pupil) gather in a dark room. The old man is bald and has a long beard. He lies in a canopy bed and reads a book. There is another book on a stool beside his bed. The young man stands beside the bed. He pulls a curtain back with his right hand and holds the old man’s hand with his left hand. The eyepiece of a telescope is visible beside the young man, and there appears to be a globe beside the old man’s bed. Full-page illustration contained within a single-ruled border.
