* the ''Eastern Council of Blachernae'' (Constantinople) in 1285. At this council, a significant statement was produced addressing the theological issue of the 'Filioque'. Despite the concern of Byzantine theologians to oppose the idea of the Filioque and its addition to the creed, there is no reference to it in the '''''Synodikon of Orthodoxy''''' <ref> a collection containing more than sixty anathemas representing the doctrinal decisions of Eastern councils through the fourteenth century.</ref>;

* the original icon of [[Theotokos of Tikhvin|Tikhvin]] ([[Panagia Hodegetria|Hodegetria]]), painted by the Holy [[Apostle Luke]] and kept in the Church of Blachernae for about five hundred years. It was sent to Russia in 1383, before the fall of Constantinople. It is said that fishermen saw it surrounded in lights over the Lake of Ladoga in Russia. The icon was later found on the bank of the Tikhvin River and was placed in the local church. Recently, the icon was kept in Chicago and returned to Russia.
