The Medieval Church · c. 1420–1429
On the Sacred Liturgy and the Rites of the Church
Symeon of Thessalonica · d. 1429
What it is
A complete explanation of Orthodox worship — the church building, all the sacraments, the funeral rites, the ordinations — by the last archbishop of the city before it fell.
Why it lasted
The most comprehensive account of Byzantine liturgy ever written, and the standard authority for Orthodox liturgical practice since.
Where to read it
This work is in the public domain and can be read in full, free, at the archives below. The Library catalogues it; it does not host the text.
These open a search on each archive rather than a direct link, which is the honest way to point at an edition nobody here has checked line by line.
