Jerusalem 121 & Paris 44 Erévan 985
The 13th September, dedication The 13th September, dedication of the Holy Places of Jerusalem of the Holy Places of Jerusalem which one makes for eight days. The first day at the Holy Anastasis The first day at the Holy Anastasis.
The second day, on assembling at the Holy Martyrium the same canon is performed. And, the same day, one displays the venerable cross to all assembled.
Paris 44 assigns the date of the feast to 23rd September. But since we know that the Martyrium basilica was dedicated on the 13th September, this is probably a copyist's error.
Although ms Jer 121 and Paris 44 describe only a two day celebration, both Egeria and the Georgian sources allot eight days to the Encaenia.
