* The Venerable [[Bede]] is our sort. His work covered much the same sort of scope as ours.
* St. Nikodemos of the Holy Mountain. In another time and place he surely would have been an editor of an encyclopedia. His work on the Rudder, the Synaxarion (and not simply translation, but attempts to unravel the historicity of some accounts that had suffered conflation or other confusion), the Philokalia; his commentaries on liturgical texts, etc., all indicate an encyclopedic mind that loves the orderly presentation of valuable knowledge.
:I'm going to suggest Saint [[John of Damascus]]. a great synthesizer, compiler, apologist, and martyr. <br>His feast day is '''Dec. 4th'''. You can look up his life, troparion and kontakion at [http://www.oca.org/FSlives.asp on OCA.org] or view his Wikipedia article Links: [http://en.wikipedia.org/wiki/John_of_Damascus here].
