When Jupiter made Man, he gave him two Wallets; one for his neighbour's
faults, the other for his own. He threw them over the Man's shoulder,
so that one hung in front and the other behind.
The Man kept the one in front for his neighbour's faults, and the one
behind for his own; so that, while the first was always under his nose,
it took some pains to see the latter.
This custom, which began thus early, is not quite unknown at the
present day.
