What's not to love about this Vaticam manuscript illustration [Vat. lat. 3868 (2r)], leading off a collection of plays by Terence?
The two on the left and right are wearing dramatic masks, of course; but I love the way they look like space aliens. And I love, too, that the anonymous Vatican librarian, when applying the library stamp, took care to place it where he did, in harmony with the bigger circle above. Lovely stuff.
