While browsing around, looking for a particular illustration of a medieval great hall, I happened upon the above picture, which is an imagining of the hall at Eltham Palace toward the end of the 15th century. I think, but can’t be sure, that the king seated splendidly at the far end is Edward IV. But it could be Richard III, or even (heaven forfend) Henry VII. The likelihood seems to be Edward.
This link will take you to an English Heritage site all about Eltham. It contains some wonderful illustrations, showing Eltham from the outside, and this view of the great hall. The whole site is well worth saving somewhere in your myriad files.
Of course, being a Ricardian, I am certain there is something essential missing from the gathering. So here it is again (mirrored for artistic reasons) with Richard himself to make it complete!
