The Eastern Orthodox Church commemorates the "Holy Fathers of the 4th Ecumenical Council, who assembled in Chalcedon" on the Sunday on or after July 13.  ; however, in some places (e.g. Russia) on the former date is rather a feast of the Fathers of the First Six Ecumenical Councils.
For the former of these is written complete propers, "The office of the 630 holy and god-bearing Fathers of the 4th ... summoned against the Monophysites Eftyches and Dioskoros ...", composed in the middle of the 14th century by Philotheos, the Patriarch of Constantinople. This contains numerous hymns exposing the council's teaching, naming its leaders whom it praises them and whose prayers it implores, and naming its opponents pejoratively. e.g., "Come let us clearly reject the errors of ... but praise in divine songs the the fourth council of pious fathers."
Also, in some places, there is another commemoration of the council on May 22.
