I agree with most of you regarding Tolkien`s use of height MOST of the times correspondingly to might, except that you forgot one, a very important one if you ask me, what about Hùrin "thalion" (wich by the way is the only character with this distinctive name wich means powerful or so i remember from the SIL.) he is said to be not as tall as his brother Húor and yet he was given lordship over the house of Hador Lórindol and he also is said to be the most powerful of the race of men ever lived ( probably only powerful in terms of warfare and strength dunno
) but thats an example, and here´s another tought regarding mighty people in tolkien´s writing : have you ever noticed that amongst the children of Ilúvatar the ones with blond hair and clear eyes are sometimes if not always ranked as above all others in terms of beauty and might??? im lacking in examples right now as i dont have the books with me but thats the impresion í´ve got after reading the SIL the last couple of times.... i know this is probably off topic and perhaps a theme for another discussion, but what do you think
