Peace and all Good!
Does anyone knows if in the Sunday of Orthodoxy the anathemas against J. Italos ("Anathema upon those who go through a course of Hellenic studies and are taught not simply for the sake of education but follow these empty notions and believe in them as the truth, upholding them as a firm foundation to such an extent that they lead others to them, sometimes secretly, sometimes openly, and then without hesitation.
Anathema upon those who of their own accord invent an account of our Creation along with other myths, who accept the Platonic Forms as true, who say that matter possesses independent substance and is shaped by the Forms, who openly question the power of the Creator to bring all things from non-existence to existence, and as their Creator to impose a beginning and end on all things in the manner of their Lord and Master") are read during Divine Liturgy?
According to John Meyendorff ("Byzantine Theology: historical trends and doctrinal themes) this anathemas were added (in 843) to the Synodikon to be read on the Sunday of Orthodoxy. What I would like to know is for how long they were read or if they are read nowadays.

Since Italos died in the 11th century, obviously the anathemas pertaining to him were added to the Synodikon after 843. Which anathemas are read, and which are omitted, varies from jurisdiction to jurisdiction. A number of the later ones tended to be more political than theological.

You're right. The first ten anathemas against Italos were added in 1076-1077 and the final one in 1082 (Meyendorff, p. 63).
