Lion of Saint Mark
It is commonly called the Greek or Eastern Orthodox Patriarchate of Alexandria to distinguish it from the Coptic Orthodox Patriarchate of Alexandria, which is part of Oriental Orthodoxy. Members of the Greek Orthodox Patriarchate were once referred to as "Melkites" by non-Chalcedonian Christians because they remained in communion with the Ecumenical Patriarchate of Constantinople after the schism that followed the Council of Chalcedon in 451. Mark the Evangelist is considered the founder of the See, and the Patriarchate's emblem is the Lion of Saint Mark.
