The Impossible Scaffolding
This scaffolding is supported by two vertical, square poles connected by layers of crossbeams. Transverse boards form a horizontal platform - supporting the bucket of water. On this platform, the workers can go about their business. The absurdity of this scaffolding becomes apparent when one realizes that the lowest of the crossbeams, against which a shovel is leaning, ought to be on the same level as the top beam, to which the pulley block is fixed.
