Third Rome
The 1650s were a time when the Russian Church, steered by Patriarch Nikon, began to place great store on renewing its ties with the older members of the Pentarchy. This emphasis dovetailed neatly with the prevailing Third Rome doctrine which saw Moscow as the successor to Constantinople. With this in mind, the metochion sent the newly recovered Byzantine relic to Moscow and was "handsomely remunerated" with 800 dinars from the Tsar's coffers.
