Hello again dear Claire!
I read with great interest what you have put into words. You're really thinking about yourself and trying to find answers, even more you are struggling.
English isn´t my mother tongue, so it is sometimes difficult for me to find the right words - but there is a saying in German, describing a real seeker - "like a dog, he is only satisfied when he incessantly has gnawed all the bone". I hope this comparison does not bother you.... What I want to say is that I admire your incessant search!!
"Beneath A Phrygian Sky" is one of my favourite songs. I love the expression "a voice from down the ages so haunting in its song" - however, the question arises: does such a voice really exist? Or is its origin simply in our own desire?
I think yes, ancient stones could tell stories! I love archaelogical sites and places steeped in history. Whenever I travel, I am drawn to these places and try to imagine how people in former times led their lives. I read that Loreena McKennitt also visited archaelogical sites in Anatolia and I think that many of her songs were created under the influence of certain places. I for myself visited Turkey four times. Away from the political situation, it is a fascinating country, the cradle of the first Christian communities....
And even if our wars should find us and we have no choice, the song asks us to proudly hold up the banner - "The truth will set us free"! That, in turn, is a gospel word of Jesus Christ, but not completely. The complete words are that, if we stay with what Jesus said, we will know the truth, and the truth will set us free. (I´d a look into the bible!)
