The following morning, after our apartment had been lowered to its daylight level and before I was permitted to leave it, a slave was sent to me by Mu Tel with instructions to stain my entire body the beautiful copper-red of my Barsoomian friends; furnishing me with a disguise which I well knew to be highly essential to the success of my venture, since my white skin would have drawn unpleasant notice upon me in any city of Barsoom. Another slave brought harness and weapons for Gor Hajus, Dar Tarus and myself, and a collar and chain for Hovan Du, the ape-man. Our harness, while of heavy material, and splendid workmanship, was quite plain, being free of all insignia either of rank or service—such harness as is customarily worn by the Barsoomian panthan, or soldier of fortune, at such times as he is not definitely in the service of any nation or individual. These panthans are virtually men without a country, being roving mercenaries ready to sell their swords to the highest bidder. Although they have no organization they are ruled by a severe code of ethics and while in the employ of a master are, almost without exception, loyal to him. They are generally supposed to be men who have flown from the wrath of their own Jeddaks or the justice of their own courts, but there is among them a sprinkling of adventurous souls who have adopted their calling because of the thrills and excitement it offers. While they are well paid, they are also great gamblers and notorious spenders, with the result that they are almost always without funds and often reduced to strange expedients for the gaining of their livelihood between engagements; a fact which gave great plausibility to our possession of a trained ape, which upon Mars would appear no more remarkable than would to us the possession of a monkey or parrot by an old salt just returned, from a long cruise, to one of our Earthly ports. This day that I stayed in the palace of Mu Tel I spent much in the company of the prince, who found pleasure in questioning me concerning the customs, the politics, the civilization and the geography of Earth, with much of which, I was surprised to note, he seemed quite familiar; a fact which he explained was due to the marvelous development of Barsoomian astronomical instruments, wireless photography and wireless telephony; the last of which has been brought to such a state of perfection that many Barsoomian savants have succeeded in learning several Earthly languages, notably Urdu, English and Russian, and, a few, Chinese also. These have doubtless been the first languages to attract their attention because of the fact that they are spoken by great numbers of people over large areas of the world.
