Dear Thymiato (censer in modern Greek if i am not wrong):
The Latinisation of the Armenian rite is a well known phaenomenon studied by scholars and recognized by the Armenian Church.
At the site of the Mother See of Holy Etchmiadzin talking about the history of the Armenian you can read about Kavazan Hovagan (Pastoral Staff or Pedum):
"During the Latin Council of Antioch, in 1141/2, to which the Armenian Catholicos Gregory III was also invited, theological and ritual differences between the Armenian and Latin Churches were discussed. Returning to Rome the Pope’s envoy, praised the Armenian Catholicos and his brother Nerses Shnorhali to Pope Innocent II.The Pope of Rome wrote a letter to the Armenian Catholicos, in which he recognized the Orthodoxy of the Armenian Church and for the complete unification of the two Churches suggested that the Armenians should mix water in the Chalice and celebrate Christmas on the 25th of December. Innocent II also presented the Armenian Catholicos with an Episcopal staff
, which began to be used by bishops. The eastern Greek-Cappadocian staff was used by archimandrites only".http://www.armenianchurch.org/index.jsp?sid=1&id=60&pid=10
