This
end-view of the Queen's footstool clearly shows our use of "through"
mortise-and-tenon joints. Through joints are so named because the tenon
extends all the way through the mortise, showing on the outside of the work piece.
Through mortise and tenon joints can be seen in many, many medieval
illustrations, including Vincenzo Foppa's Young Ciciero Reading (c. 1460)
and Ambrogio Borgognone's Madonna and Child. Reproductions of these
paintings can be found in Ball and Campbell's Master Pieces (p. 10).
Additional examples can be found in Percy Macquoid's A History of English
Furniture: Volume One, The Age of Oak, 1500-1660 ( pp 70 - 71). Oak
Furniture, the British Tradition: A History of Early Furniture in the British
Isles and New England, by Victor Chinnery, has examples on pp 108, 260
- 262. Finally, three examples of benches of this type with similar
stretchers can be found at the New York Metropolitan Museum of Art's Cloisters
Annex in the Campin room off of the Boppard room.
