Harold Knight’s The Breakfast Table 1927 – painted 450 years after yesterday’s madonna and child but in a straight line of descent from it, linked not just because of the glorious pink both women are wearing but because their preoccupations are so similar  – the detail may be different but the essentials are the same. (The Harold Knight painting has recently been sold and its whereabouts are unknown – someone, somewhere is looking at it and we hope they love it as much as we do.)
