The Head of Caesar is a short story by Gilbert Keith Chesterton: There is somewhere in Brompton or Kensington an interminable avenue of tall houses, rich but largely empty, that looks like a terrace of tombs. The very steps up to the dark front doors seem as steep as the side of pyramids; one would hesitate to knock at the door, lest it should be opened by a mummy. But a yet more depressing feature in the grey facade is its telescopic length and changeless continuity. The pilgrim walking down it begins to think he will never come to a break or a corner; but there is one exception--a very small one, but hailed by the pilgrim almost with a shout. There is a sort of mews between two of the tall mansions, a mere slit like the crack of a door by comparison with the street, but just large enough to permit a pigmy ale-house or eating-house, still allowed by the rich to their stable-servants, to stand in the angle. There is something cheery in its very dinginess, and something free and elfin in its very insignificance. At the feet of those grey stone giants it looks like a lighted house of dwarfs.
