Here is an excerpt from his most recent entry:
Parts of the Church Building: the Altar Rail
Continuing our series on the parts of the church building, St. Germanus goes on to say:
8. The entablature is the legal and holy decoration, representing a depiction of the crucified Christ by means of a decorated cross.
9. The chancel barriers indicate the place of prayer: the outside is for the people, and the inside, the Holy of Holies , is accessible only to the priests. The barriers, made of bronze, are like those around the Holy Sepulchre, so that no one might enter there by accident.
An entablature is a decorated beam supported by either a wall or at least two columns. (More on that here.) In this case, it is supported by columns as St. Germanus is referring to the barrier dividing the nave from the chancel, or sanctuary. In fact, the word chancel derives from the Latin word for gates, cancelli (pronounced kan-chelly).
However, St. Germanus is not describing what we call a chancel screen in the West. A chancel screen separates the nave (the area traditionally reserved for the laity) from the choir and the sanctuary (the area traditionally reserved for clergy). The barrier St. Germanus describes separates the sanctuary from the choir. It is the boundary of the Holy of Holies, and is the forerunner of the eastern iconostasis and the western altar rail.

While inviting you to read the remainder there, I cannot resist showing you this image, which Dino shares later on in his article, of the beautiful Church of Elijah the Prophet in Yaroslavl, Russia.
