I'm too lazy to look through all of the posts to see if this has been already dealt with...
I googled "hymn of one" and came across this Wikipedia page.
http://en.wikipedia.org/wiki/Troparion
Apparently,
"A troparion in Byzantine music and
religious music of Eastern Orthodoxy is a short
hymn of one stanza, or one of a series of stanzas (this may carry the further connotation of a hymn interpolated between psalm verses)."
And that's not all...
"A troparion to the Mother of God (Theotokos) is called a theotokion."
From
http://en.wikipedia.org/wiki/Theotokos
"Theotokos is a title of Mary, the mother of Jesus."
Despite Bree's comment about her not being a Christian, perhaps the Hymn of One had some ties to Christianity and Jesus?
If there is a troparion (a hymn of one) dedicated to the Virgin Mary called a theotokion, then what other Christian ties could there be?
It also mentions several things linking a troparion and Theotokos to Eastern Orthodoxy. Notable?
If this has already been hashed through, please excuse me, and tell me if there is any notable details about this.
