Not sure how relevant this is but on patriarchal cross in Portugal from A Treatise On Ecclesiastical Heraldry by John Woodward: The title of patriarch was given to archbishops of metropolis, perhaps who had other metrolitans under them. Patriarchs have the right to use in the emblem of their dignity a cross with two bars. Roderid da Cunha, Archbishop of Braga and Primate of Portugal used such a cross. The patriarchal cross symbolises the powers of two offices in the same person: Metropolitan in own province but also having authority over other Metropolitans. The use of this symbol is very old. The patriarchate of Lisbon and the Indies was instituted by Clement XI in 1716. The archbishop of Toledo is the Primate of Spain since 1085 but the Archbishop of Braga in Portugal claims the Primacy of the whole peninsula and uses the double cross.
