Read Winter is Coming: Symbols and Hidden Meanings in A Game of Thrones for Free Online Page A

Jon part, the men who ordered all Targaryens dead still live, and King Robert is visiting. There’s still a need to keep the secret.
    Likewise, Bran and Jon have intriguing dreams that there’s an important secret about Jon in the crypts, where Lyanna is buried ( see Jon’s Dreams ). Certainly, if he is their son, this would make him a child of ice and fire with Winterfell warg powers and dragon magic, the hero of prophecy. In his studies, did Rhaegar see prophecies pointing to such a child? If Jon is a Targaryen, he shares Daenerys’s ancient magic and her destiny: A child of the forest said that “the prince that was promised would be born of their line,” the line of Mad King Aerys and Rhaella (V:300-301).
    Rhaegar believed in this destiny and insisted that he must have three children to mimic Aegon the Conqueror and his two sister-wives, that “there must be one more,” since “the dragon has three heads.” However, his wife was infertile afterward, and he may have tried to conceive a third child with Lyanna. This may have been rape, but naming it the “Tower of Joy” suggests love. Either way, he kept Lyanna close and they were indisputably lovers.
    It should be noted that the Targaryens practiced bigamy. Though this was basically in the distant past, Rhaegar considered his children to be Aegon the Conqueror and his sisters reborn, so he might have wed Lyanna secretly, repeating the cycle of Aegon and his double marriage. Naming his son and daughter after Aegon the Conqueror and his sister Rhaenys emphasizes this and also suggests he was awaiting a third child to name Visenya, and complete the pattern. As a bastard, Jon is not technically in the succession (though he would still be heir to Targaryen dragon magic, destiny, and prophecy). If he is a trueborn son, Jon would be in line after his older half-brother Aegon, if he is alive, and before Daenerys, his aunt and later in the succession. (It should also be noted that since the civil war called the Dance of the Dragons, females are specifically barred from the throne. Her son would inherit in her place.)
    If Jon’s parents were married, it once again seems unlikely Ned would let him go to the Wall if he knows Jon is the Targaryen heir. (On the other hand, Ned is loyal to Robert and wants peace in the realm, so he may be willing to sweep Jon’s nebulous claim under the rug. The Targaryens were conquered, after all.) It’s more likely Jon’s parents were not married. Ned would believe that as a bastard, Jon might as well find safety and honor at the Wall, since he’s not a trueborn heir.
    Aegon the Conqueror reborn is certainly Daenerys, who with her three dragons will come from over the sea and conquer Westeros. To do this, she will likely need two male dragonriders as partners and (possibly) husbands. Bastard or no, if Jon is Rhaegar’s son, he, like young Aegon Targaryen, is prophesized to be Daenerys’s perfect mate. Martin comments only, “Jon’s parentage will be revealed eventually,” though we had little cause to doubt it. 13

Section II: Born Again Amidst Smoke and Salt: Exploring Prophecy
    T he book series offers several important prophecies that drive the narrative and point toward where the heroes are heading. In the House of the Undying on the show, Daenerys has an emotional meeting with her lost husband and son, but does not see the book’s visions of the future or hear the prophecies that will drive her life. The reason for this, as Martin pointed out at the World Science Fiction and Fantasy Convention, is clear: The producers had no guarantee that the show would last until all the prophecies could be fulfilled, or for that matter, that minor threads, characters, and subplots wouldn’t be cut for time. As such, they didn’t wish to promise prophecies that might or might not be completed within the show. The book has more freedom, as Martin is certain of major events.
    There are other sources of prophecy as well. Maegi appear to
