The story of the Tower of Babel (like that in The Suicide of Saul, Bruegel's only other painting with an Old Testament subject) was interpreted as an example of pride punished, and that is no doubt what Bruegel intended his painting to illustrate. Moreover, the hectic activity of the engineers, masons and workmen points to a second moral: the futility of much human endeavour. Nimrod's doomed building was used to illustrate this meaning in Sebastian Brant's "Ship of Fools". Bruegel's knowledge of building procedures and techniques is considerable and correct in detail. The skill with which he has shown these activities recalls that his last commission, left unfinished at his death, was for a series of documentary paintings recording the digging of a canal linking Brussels and Antwerp.
