With the official George R.R. Martin-approved artwork of Elia in The World of Ice & Fire book looking exactly like Princess Sibylla in the movie Kingdom of Heaven played by the incredibly gorgeous Eva Green:
And then the official artwork for celebrating the 10th anniversary of The World of Ice and Fire, featuring the House of the Undying vision of Elia, Rhaegar and their son Aegon, in it the artist draws Elia looking like this:
And then book quotes like this:
"She was," said Meera, hopping over a stone, "but there were others fairer still. One was the wife of the dragon prince, who'd brought a dozen lady companions to attend her."
- A Storm of Swords - Bran II
"Early in the year 279 AC, Rhaegar Targaryen, Prince of Dragonstone, was formally betrothed to Princess Elia Martell, the delicate young sister of Doran Martell, Prince of Dorne."
- The World of Ice and Fire - The Targaryen Kings: Aerys II
"The crowning of the Stark girl, who was by all reports a wild and boyish young thing with none of the Princess Elia's delicate beauty, could only have been meant to win the allegiance of Winterfell to Prince Rhaegar's cause."
- The World of Ice and Fire - The Fall of the Dragons: The Year of the False Spring
And, finally, GRRM saying this in the official announcement titled The Mad King Is Coming, of the upcoming stage play The Mad King, on his blog:
"The fairest flowers of the Seven Kingdoms will attend to cheer them on, including Ashara Dayne, with her laughing purple eyes, and the Dornish beauty Elia Martell, Prince Rhaegar’s lady wife."
After all this, how am I meant to see Elia as anything other than stupidly beautiful?
