"Ah, Thuvia of Ptarth," he cried, "you are cold even before the fiery blasts of my consuming love! No harder than your heart, nor colder is the hard, cold ersite of this thrice happy bench which supports your divine and fadeless form! Tell me, O Thuvia of Ptarth, that I may still hope—that though you do not love me now, yet some day, some day, my princess, I—"
The girl sprang to her feet with an exclamation of surprise and displeasure. Her queenly head was poised haughtily upon her smooth red shoulders. Her dark eyes looked angrily into those of the man.
"You forget yourself, and the customs of Barsoom, Astok," she said. "I have given you no right thus to address the daughter of Thuvan Dihn, nor have you won such a right."
The man reached suddenly forth and grasped her by the arm.
"You shall be my princess!" he cried. "By the breast of Issus, thou shalt, nor shall any other come between Astok, Prince of Dusar, and his heart's desire. Tell me that there is another, and I shall cut out his foul heart and fling it to the wild calots of the dead sea-bottoms!"
At touch of the man's hand upon her flesh the girl went pallid beneath her coppery skin, for the persons of the royal women of the courts of Mars are held but little less than sacred. The act of Astok, Prince of Dusar, was profanation. There was no terror in the eyes of Thuvia of Ptarth—only horror for the thing the man had done and for its possible consequences....
Aiming his work at the pulps, Burroughs had his first story, Under the Moons of Mars, serialized by Frank Munsey in the February to July 1912 issues of The All-Story – under the name "Norman Bean" to protect his reputation. Under the Moons of Mars inaugurated the Barsoom series and earned Burroughs. It was first published as a book by A. C. McClurg of Chicago in 1917, entitled A Princess of Mars, after three Barsoom sequels had appeared as serials, and McClurg had published the first four serial Tarzan novels as books.
Burroughs soon took up writing full-time and by the time the run of Under the Moons of Mars had finished he had completed two novels, including Tarzan of the Apes, published from October 1912 and one of his most successful series.
Burroughs also wrote popular science fiction and fantasy stories involving Earthly adventurers transported to various planets (notably Barsoom, Burroughs's fictional name for Mars, and Amtor, his fictional name for Venus), lost islands, and into the interior of the hollow earth in his Pellucidar stories, as well as westerns and historical romances. Along with All-Story, many of his stories were published in The Argosy magazine.
Tarzan was a cultural sensation when introduced. Burroughs was determined to capitalize on Tarzan's popularity in every way possible. He planned to exploit Tarzan through several different media including a syndicated Tarzan comic strip, movies and merchandise. Experts in the field advised against this course of action, stating that the different media would just end up competing against each other. Burroughs went ahead, however, and proved the experts wrong – the public wanted Tarzan in whatever fashion he was offered. Tarzan remains one of the most successful fictional characters to this day and is a cultural icon.
In either 1915 or 1919, Burroughs purchased a large ranch north of Los Angeles, California, which he named "Tarzana." The citizens of the community that sprang up around the ranch voted to adopt that name when their community, Tarzana, California was formed in 1927. Also, the unincorporated community of Tarzan, Texas, was formally named in 1927 when the US Postal Service accepted the name, reputedly coming from the popularity of the first (silent) Tarzan of the Apes film, starring Elmo Lincoln, and an early "Tarzan" comic strip.
In 1923 Burroughs set up his own company, Edgar Rice Burroughs, Inc., and began printing his own books through the 1930s.
