The man is depicted in a seated position, with his hands clasped in front of him and his head slightly tilted to the side. The woman is wearing a long, flowing dress and has her hair tied up in a bun. The ruler is a standard measuring scale, with the ruler's scale at one end and the agate stone at the other.
