In MN77 the Buddha says he sometimes eats more than one bowlful, full to the rim, of food.
But sometimes I even eat this bowl full to the brim, or even more.
Ahaṃ kho pana, udāyi, appekadā iminā pattena samatittikampi bhuñjāmi bhiyyopi bhuñjāmi.
Were the bowls a lot smaller then? More like the one that Bhante @Sujato carries, than the 7 inch bowl many monastics carry these days.
It is my belief that the larger bowls came about to help carry and store things while on ‘tudong’/wandering.
Is there archaeological or other evidence showing how bowls might have ‘grown’?
Just a random pondering I’ve had while eating my lunch
