He descended the slope and approached the band near enough to see distinctly the flags, make out the colours and distinguish the devices they bore, especially one on a standard or ensign of white satin, on which there was painted in a very life-like style an ass like a little sard, with its head up, its mouth open and its tongue out, as if it were in the act and attitude of braying; and round it were inscribed in large characters these two lines-- They did not bray in vain, Our alcaldes twain.
From this device Don Quixote concluded that these people must be from the braying town, and he said so to Sancho, explaining to him what was written on the standard.

At the same time he observed that the man who had told them about the matter was wrong in saying that the two who brayed were regidors, for according to the lines of the standard they were alcaldes.

To which Sancho replied, "Senor, there's nothing to stick at in that, for maybe the regidors who brayed then came to be alcaldes of their town afterwards, and so they may go by both titles; moreover, it has nothing to do with the truth of the story whether the brayers were alcaldes or regidors, provided at any rate they did bray; for an alcalde is just as likely to bray as a regidor." They perceived, in short, clearly that the town which had been twitted had turned out to do battle with some other that had jeered it more than was fair or neighbourly.
Don Quixote proceeded to join them, not a little to Sancho's uneasiness, for he never relished mixing himself up in expeditions of that sort.

The members of the troop received him into the midst of them, taking him to be some one who was on their side.

Don Quixote, putting up his visor, advanced with an easy bearing and demeanour to the standard with the ass, and all the chief men of the army gathered round him to look at him, staring at him with the usual amazement that everybody felt on seeing him for the first time.
