The Roman bishop of the Catholic church is often wearing a mitre. Countless sites, 'that really know the hidden truth and tell it', make the connection of 'fish mouth' and 'Dagon priest', claiming that the hat has a direct, long and unbroken tradition, like:
The Mitre Hat
The priests of Dagon were known by their “Mitre Hat” which resembled an open mouth of a fish. The same exact hat wore even today by The Pope as well as Cardinals and Bishops. All “priests of Dagon” and the religion that surrounds them, even to this day, is identical to that born in Babylon.

The Mitre hat that is worn by Catholic priests, cardinals and the Pope, represents Dagon the Babylonian fish god. The ancient Babylonians worshiped Dagan, the god of agriculture, plenty (food) and good fortune.
The Babylonian priests wore a headdress that represented the worship of Cybele and Dagon. It featured an open-fish mouth on the head, with the rest of the fish body forming a cloak.
In the Roman Empire, it was worn by the head priest of Cybele (the Magna Mater) or the Great Queen Mother Goddess.
Today the Catholic Cardinals, Bishops and the Pope all wear the open fish-mouth mitre, which represents the worship of Cybele and Dagon.
The Mitre hat of Dagan is always worn over the Kippa of Ashtoreth/Cybele, as you can see in the picture of Pope Francis I.
–– Roman Catholic Beliefs: Who Is The Roman Catholic Church Really Worshiping?
As the Pope bears the key of Janus, so he wears the mitre of Dagon. The excavations of Nineveh have put this beyond all possibility of doubt. The Papal mitre is entirely different from the mitre of Aaron and the Jewish high priests.
That mitre was a turban. The two-horned mitre, which the Pope wears, when he sits on the high altar at Rome and receives the adoration of the Cardinals, is the very mitre worn by Dagon, the fish-god of the Philistines and Babylonians. There were two ways in which Dagon was anciently represented. The one was when he was depicted as half-man, half-fish; the upper part being entirely human, the under part ending in the tail of a fish. The other was, when, to use the words of Layard, "the head of the fish formed a mitre above that of the man, while its scaly, fan-like tail fell as a cloak behind, leaving the human limbs and feet exposed. Of Dagon in this form Layard gives a representation in his last work, which is here represented to the reader (Fig. 48); and no one who examines his mitre, and compares it with the Pope's, as given in Elliot's Horoe, can doubt for a moment that from that, and no other source, has the pontifical mitre been derived. The gaping jaws of the fish surmounting the head of the man at Nineveh are the unmistakable counterpart of the horns of the Pope's mitre at Rome.

The claim of interest for Skeptics is not about any belief that might build on the alleged symbolism. The basic claim to be analysed is solely to focus on the assertion that 'the bishop mitre was directly adopted from Babylonian priests and their head coverings'. That is a verifiable or falsifiable materialist angle.
This claim is widespread and influential. It rests in most presentations of this claim mainly on two pictorial 'evidences' of antiquity and a resemblance to modern bishop's mitres.
And if not always claimed directly, it at least always assumes and sometimes directly states that there is an unbroken tradition – rooted in the direct adoption of pagan beliefs and symbolism - of clerical headgear.
This is quite a colourful explanation. But is it true? What are the origins of and influences on the pope's headgear?
More specifically: Was it adopted by the Christian church from Mesopotamian headgear that the priests of Dagon wore?
