A knight was known to be a knight-errant by his riding through the peaceful country in full armour, with a single squire at his back, as surely as a man is now recognised as a fox-hunter who is seen riding easily along the strip of green sward by the roadside in a pink coat and velvet cap. "Fair knight," says Sir Tristram, to one whom he had found sitting by a fountain, "ye seem for to be a knight-errant by your arms and your harness, therefore dress ye to just with one of us:" for this was of course inevitable when knights-errant met; the whole passage is worth transcribing:--"Sir Tristram and Sir Kay rode within the forest a mile or more. And at the last Sir Tristram saw before him a likely knight and a well-made man, all armed, sitting by a clear fountain, and a mighty horse near unto him tied to a great oak, and a man [his squire] riding by him, leading an horse that was laden with spears. Then Sir Tristram rode near him, and said, 'Fair knight, why sit ye so drooping, for ye seem to be an errant knight by your arms and harness, and therefore dress ye to just with one of us or with both.' Therewith that knight made no words, but took his shield and buckled it about his neck, and lightly he took his horse and leaped upon him, and then he took a great spear of his squire, and departed his way a furlong." And so we read in another place:--"Sir Dinadan spake on high and said, 'Sir Knight, make thee ready to just with me, for it is the custom of all arrant knights one for to just with another.' 'Sir,' said Sir Epinogris, 'is that the rule of your arrant knights, for to make a knight to just whether he will or not?' 'As for that, make thee ready, for here is for me.' And therewith they spurred their horses, and met together so hard that Sir Epinogris smote down Sir Dinadan"--and so taught him the truth of the adage "that it is wise to let sleeping dogs lie." But they did not merely take the chance of meeting one another as they journeyed. A knight in quest of adventures would sometimes station himself at a ford or bridge, and mount guard all day long, and let no knight-errant pass until he had jousted with him. Thus we read "then they rode forth all together, King Mark, Sir Lamorake, and Sir Dinadan, till that they came unto a bridge, and at the end of that bridge stood a fair tower. Then saw they a knight on horseback, well armed, brandishing a spear, crying and proffering himself to just." And again, "When King Mark and Sir Dinadan had ridden about four miles, they came unto a bridge, whereas hoved a knight on horseback, and ready to just. 'So,' said Sir Dinadan unto King Mark, 'yonder hoveth a knight that will just, for there shall none pass this bridge but he must just with that knight.'"
