I did not expect much agrobiodiversity in the Victoria & Albert’s exhibition on the baroque. But I found some anyway, in the mid-17th century Flemish oil painting Flower Garland with the Holy Sacrament and an Angel’s Head, possibly by Daniel Seghers (1590-1661). It’s reproduced below, but you can consult a better image on Flickr.
It looks to me that what I’ve marked are maize cobs, although the one on the right could, I suppose, be sorghum. If they are maize, it is interesting that they seem to show three distinct varieties. There’s variation in the other cereals too. I guess it goes with the general exuberance of the baroque. But what’s with those peduncles?
