Lomonosov?
Washington?
What other version?
And the approximate time of creation.

$ 41.5 h33, oil on wood (what?).

Judging by attributes, perhaps, shows the founder of crystallography Roma Jean-Baptiste de Lisle (Jean-Baptiste Romé de L'Isle, 1736 - 1790).

It is possible that the work was commissioned later by any educational institution.
