Does anyone else find it odd that the characterization( i invented a word! [img]smilies/biggrin.gif[/img]) of the moon is male? In the usual mythologies, the Moon is often portrayed as female (eg: Artemis, Diana) Did Tolkien have a reason for it, or did he just pull it out of thin air?
(trivial question, I know, but it wouldnt leave me alone)
