My fave xmas related medieval motif is the Dream of the Magi (where they are warned in their sleep not to return to Herod), but here they are three Kings snuggling.
Or this one from St Lazare, in Autun: big spoon, little spoon and middle spoon
here they are, just sort of stacked on top of each other
Cosy Kings, in their pjs
In some stained glass, seemingly newly awakened:
Cuddling and confused, there is an angel in the room:
when ur napping in a field (?) and get woken up
clearly they have a busy schedule, but it is nice that they can take some time to nap
and lastly, one final marginal illustration of this snuggling throuple.
