You are absolutely right.
My only excuse for the mistake is my hurry in finishing the quotes for the queue I used, when I was traveling.
I was looking for the correct name of the statue and snatched up the words ‘great stone Kings of Argonath’ a few lines above. I even thought: ‘Yay, I learned something new!’
Of course that sentence was only describing a resemblance to the stone Kings of Argonath.
I apologise and thank you for pointing it out!
(It’s now ‘About the Statue at the Cross-Roads’ ;))
