Not getting a theming bonus I think I should get

I am Brazil. In the Hermitage, I have:

England, Renaissance (Portrait of Bindo Altoviti)
Kuala Lumpur, Classical (Necklace)
Carthage, Medieval (Kindred Spirits)

The theming bonus is for the "great work slots are all filled with Art from different Eras and different Civilizations".

I think I have this- what am I missing?

The artifact (Kuala Lumpur necklace) doesn't count in this building. You need works of art (paintings).

Ah yeah. That was it. Kind of silly. They should use a different icon for artifacts.
