George R.R. Martin is doing press to promote his latest book, The World of Ice & Fire: The Untold History of Westeros and the Game of Thrones, and he's once again addressing how the popular version of the Iron Throne doesn't match his vision.

"I said repeatedly the Iron Throne is huge. It towers over the room like a great beast. And it's ugly. It's asymmetric. It's put together by blacksmiths not by craftsmen and experts in furniture manufacturing," Martin said, as reported by Business Insider. "You have to walk the iron steps and when a king sits on it he's like 10 feet above everybody else ... He's in this raised position looking down on everyone."

Martin wrote a blog post in 2013 talking about where HBO went wrong with its design. "The HBO throne is none of those things. It's big, yes, but not nearly as big as the one described in the novels," he wrote. "And for good reason. We have a huge throne room set in Belfast, but not nearly huge enough to hold the Iron Throne as I painted it."

"For that we'd need something much bigger, more like the interior of St. Paul's Cathedral or Westminster Abbey, and no set has that much room," he continued. "The Book Version of the Iron Throne would not even fit through the doors of the Paint Hall."

Martin worked with artist Marc Simonetti to pain the Iron Throne as it exists in his head and as described in the books, and the result is included in The Untold History of Westeros and the Game of Thrones. The image has already appeared in a Game of Thrones calendar, but now it's included in an actual book in the series of novels, and readers can see Martin's own vision for the throne.

Here's part of the image that appears in the book:
