Bright Week Reading - Paschal Canon Annotated
St. John of Damascus - traditional author of the Canon of Pascha
I found this interesting annotated Paschal Canon at Archimandrite Ephrem's site. Click his link to get the PDF. He is working on translating many things from the Greek into English which heretofor have not been translated, and providing some annotated liturgical texts, relying on St. Nikodemos' notes on the liturgical texts. It would be helpful to have some knowledge of Greek, but I don't think you need to be a sophisticated Greek student to get some value out of the footnotes.
It is VERY interesting (although somewhat academic, in the best sense) to learn where these liturgical texts we sing actually derive from.
