7. Of ARMENIA. A second Gregory was patriarch of Armenia about the end of the thirteenth and commencement of the fourteenth century. He was disposed to unite with the Roman rather than the Greek church. A letter of his to Hayton, king of Armenia, is given in the Conciliatio Ecclesiae Armeniae cum Romano of Galenus. (Cave, Hist. Litt. vol. ii. p. 337.)
