I'll try and work back over and start with the more recent. So firstly a few from the 17th century. This first is titled A Young Astronomer and is by the Dutch painter Olivier van Deuren.
Next up a portrait of Emperor Charles V. It's by the artist Parmigianino, dates from the first half of the 16th century, and shows a quite impressively detailed globe.
And finally, going way back, this image of Henry II, Holy Roman Emperor. I'm not sure quite what it is he's holding, but it looks very globe (or disc) like. He's holding it in much the same way that kings hold the Globus cruciger (orb surmounted by a cross) in images. It's said that the orb symbolises the earth. So if that's the case we might be able to take it as some evidence that people knew the earth was globular back then. The picture below this one also shows Henry II - this time with a more classic looking Globus.
