[7] The passage excerpted from the Euthymiac History is usually regarded as an interpolation, although every surviving copy of the sermon includes it.
[1] The same tradition, perhaps also drawn from the Euthymiac History, is found in Cosmas Vestitor's fourth sermon on the Dormition.
The same episode in similar language is related in Theophanes the Confessor, but he does not cite the Euthymiac History.
According to the excerpt, at the time of the council of Chalcedon in 451, the Emperor Marcian and Empress Pulcheria asked Patriarch Juvenal of Jerusalem to have relics of Mary, mother of Jesus, sent to Constantinople.
Upon being told this, the imperial couple requested the garment and, after his return, Juvenal had it sent to Constantinople, where it was placed in a church in Blachernae.
That a robe purportedly belonging to Mary arrived in Constantinople in a casket at some point before the 7th century is certain, and the Euthymiac History may contain an accurate account of its origin.
