“What should we know,

Of the Long Ago,
Were it not for Verse:”
—Oliver St. John Gogarty (1878–1957)
“The meeting in the open of two dogs, strangers to each other, is one of the most painful, thrilling, and pregnant of all conceivabale encounters; it is surrounded by an atmosphere of the last canniness, presided over by a constraint for which I have no preciser name; they simply cannot pass each other, their mutual embarrassment is frightful to behold.”
—Thomas Mann (1875–1955)
