Below are excerpts from Fr culleton's "The Prophets & Our Times" that allude to a possible antipope:

65. Prophecy of Premol (496)


     "..... And here it is that the King of Zion (Pope?) along with his cross, with his sceptre and his triple crown, shaking off, on the ruins, the dust of his shoes, hastens to flee towards other shores. And is it not so, 0 Lord, that Your Church is rent asunder by her own children?

The sons of Zion are divided into two camps; one faithful to the fugitive Pontiff, and the other inclined or disposed to the government of Zion respecting the Sceptre, but breaking in pieces the triple crown.  

"But my spirit wanders and my eyes become obscured at the sight of this terrible cataclysm. But the Spirit said to me, that the man who hopes in God does penance, because the all powerful and merciful God will draw the world out of confusion and a new world will commence. Then the Spirit said to me: 'Here is the beginning of the end of Time which begins!' And I awoke terrified."

72a  Merlin (7th century)

There will come a German Antipope. Italy and Germany will be sorely troubled. A French King will restore the true Pope.

100. John of Vatiguerro ( 13th cent.)

     "Spoliation, devastation and pillage of that most famous city, which is the capitol and mistress of the whole kingdom of France," will take place when the Church and world will be grievously troubled: "The Pope will change his residence, the Church will not be defended for the duration of twenty-five months, and more, because during all this time there will be no Pope, no Emperor of Rome and no ruler in France. Afterwards a young captive prince shall recover the crown of the Lilies and shall extend his dominion over all the universe. Once established he shall destroy the Sons of Brutus' and their Isle so that their memory shall pass into everlasting forgetfulness.

     "After many tribulations a Pope will be elected out of those who escaped persecution. He, by his sanctity, will reform the clergy and the whole world will venerate them for their virtue and perfection. He will travel barefoot and be devoid of fear. Almost all unbelievers and the Jews will be converted and there will be one law, one faith, one baptism, one life. All people will love one another and peace will last a long time.

123o. Nostradamus

"The New Pope will be elected at this time; related to the Great Monarch. He will begin his rule at Avignon, the new capitol of France, and later be restored to Rome by the Great Monarch."

124. Gameleo

      "The Great Lion will arise when the Holy See has been moved to Mentz, and a Sabinian elected Pope. There will have been much dissension among the cardinals."

131. Rudolph Gekner (d. 1675)

     "A great prince of the North with a most powerful army will traverse all Europe, uproot all republics, and exterminate all rebels. His sword, moved by Divine power, will most valiantly defend the Church of Jesus Christ. He will combat on behalf of the true orthodox faith, and shall subdue to his dominion the Mahometan Empire. A new pastor of the universal Church (Pastor Funalis, Franciscan?) will come from the shore (of Dalmatia) through a celestial prodigy, and in simplicity of heart adorned with the doctrines of Jesus Christ. Peace will be restored to the world."

139. Capuchin Friar (1776)

     "All the ecclesiastics, both secular and regular, shall be stripped of all their possessions, and of every kind of property, and obliged to beg from lay persons their food and everything necessary for their support, and for the worship of God. All religious orders will be abolished, except one having the rules of the most rigid and most severe institute of the ancient monks. During these calamities the Pope shall die. Through the death of the Supreme Pontiff the Church will be reduced to the most painful anarchy, because from three hostile powers three popes will be contemporaneously elected: one Italian, another German, the third Greek, by force of arms, shall be placed on the throne. During this time much human blood shall be shed in Italy, and many cities, country towns, and castles shall be brought to ruin, with the death of many thousands of persons.
      "By the Catholic clergy and people the true and lawful Pope will be elected, who shall be a man of great holiness and goodness of life, selected from the surviving monastic Order mentioned above.
      "A scion of the Carlovingian race, by all considered extinct, will come to Rome to behold and admire the clemency of this Pontiff, who will crown him, and declare him to be the legitimate Emperor of the Romans, and from the Chair of St. Peter, the Pope will lift up the standard, the crucifix, and will give it to the new emperor.
       "This new emperor, with the robust Italian and French people, and with those of other nations, will form a most Powerful host, called the Church Army (see 114), through which he shall destroy the Ottoman Empire, all heresies, and shall also totally defeat the Emperor of the North, who is called Mystic Antichrist.
      "The above mentioned new emperor, with the assistance of God and of the Pope, will cooperate to the reformation of abuses; will assume (with the free consent of the Pope) the management of the temporal government; will assign a decent pension to the Supreme Pontiff, and also the bishops and clergy: and they all, being detached from earthly covetousness, will live in peace, which shall last till the end of time.
      "Finally, the Pope will select twelve subjects of his religion, whom he will send through the world to preach missions. They shall have the power of converting the nations to the faith of our Lord Jesus Christ, excepting the Hebrews, who are reserved for the end of the world."

150. Elizabeth Canori-Mora (d. 1825)

     "It seemed to me to behold the heavens opening, and St. Peter, Prince of the Apostles, coming down, surrounded with great glory and by a numerous escort of heavenly spirits, singing canticles. St. Peter was dressed in his pontifical robes, and held in his right hand the pastoral staff, with which he was drawing upon the earth an immense cross: at the same time the angels sang these words of the Psalmist, 'You will constitute them princes over the whole earth.'
     "After this the holy Apostle touched with his staff the four extremities of the cross, from which instantly sprung up four beautiful trees loaded with blossoms and fruits. These mysterious trees had the form of a cross, and were surrounded by a splendid light. Then I comprehended in the depth of my soul that St. Peter had produced these four symbolic trees to the end that they may serve as a place of refuge to the little flocks of the faithful friends of Jesus Christ, and in order to preserve them from the fearful punishment which shall convulse the whole earth. All good Christians shall then be protected under these trees, together with all those religious persons who shall have faithfully preserved in their hearts the spirit of their order. I say the same thing in relation to the secular clergy and to all other persons of every class who shall have kept in their heart the Catholic faith;  they shall all be protected. But woe, to those religious who do not observe their rule! thrice unhappy they! for they shall all be struck by that terrible punishment. I say the same to all secular clergy, and to all classes of people in the world who give themselves to a life of pleasure, and who follow the false maxims of modern ideas, which are opposed to the holy precepts of the gospel. These wretched people, who through their scandalous conduct deny the faith of Jesus Christ, shall perish under the weight of the indignant arm of God's justice. Not one of them shall be able to escape the punishment.
     "I beheld these good Christians, who had sought a refuge under those mysterious trees, in the form of beautiful lambs confided to the care and vigilance of St. Peter, their good shepherd, testifying to him the most humble and most respectful obedience. As soon as St. Peter, the prince of the Apostles, had gathered the flock of Jesus in a place of safety, he reascended into heaven, accompanied by legions of angels. Scarcely had they disappeared, when the sky was covered with clouds so dense and dismal that it was impossible to look at them without dismay. On a sudden there burst out such a terrible and violent wind, that its noise seemed like the roars of furious lions. The sound of the dreadful hurricane was heard over the whole earth. Fear and terror struck not only men, but the very beasts.

     "All men shall rise one against the other, and they shall kill one another without pity. During this sanguinary conflict the avenging arm of God will strike the wicked, and in his mighty power he will punish their pride and presumption. God will employ the powers of hell for the extermination of these impious and heretical persons who desire to overthrow the Church and destroy it to its very foundation. These presumptuous men in their mad impiety believe that they can overthrow God from His throne; but the will despise their artifices, and through an effect of His Mighty Hand He will punish these impious blasphemers by giving permission to the infernal spirits to come out from hell. Innumerable legions of demons shall overrun the earth, and shall execute the orders of Divine Justice by causing terrible calamities and disasters; they shall attack everything; they shall injure individual persons and entire families; they shall devastate property and alimentary productions, cities and villages. Nothing on earth shall be spared. God will allow the demons to strike with death those impious men, because they gave themselves up to the infernal powers, and had formed with them a compact against the Catholic Church.
      "Being desirous of more fully penetrating my spirit with a deeper sentiment of His Divine Justice, God showed to me the awful abyss; I saw in the bowels of the earth a dark and frightful cavern, whence an infinite number of demons were issuing forth, who under the form of men and beasts came to ravage the earth, leaving everywhere ruins and blood. Happy will be all true and good Catholics! They shall experience the powerful protection of the holy Apostles, St. Peter and St. Paul, who will watch over them lest they may be injured either in their persons or their property. Those evil spirits shall plunder every place where God has been outraged, despised, and blasphemed; the edifices they profaned will be pulled down and destroyed, and nothing but ruins shall remain of them.

     "After this frightful Punishment I saw the heavens opening, and St. Peter coming down again upon earth; he was vested in his pontifical robes, and surrounded by a great number of angels, who were chanting hymns in his honour, and they proclaimed him as sovereign of the earth. I saw also St. Paul descending upon the earth. By God's command, he traversed the earth and chained the demons, whom he brought before St. Peter, who commanded them to return into hell, whence they had come.
     "Then a great light appeared upon the earth which was the sign of the reconciliation of God with man. The angels conducted before the throne of the prince of the Apostles the small flock that had remained faithful to Jesus Christ. These good and zealous Christians testified to him the most profound respect, praising God and thanking the Apostles for having delivered them from the common destruction, and for having protected the Church of Jesus Christ by not permitting her to be infected with the false maxims of the world. St. Peter then chose the new pope. The Church was again organized; religious orders were re-established; the private families of ordinary Christians, through their great fervour and zeal for the glory of God, became like the most exemplary religious communities. Such is the glorious triumph reserved for the Catholic Church; she shall be praised, honoured, and esteemed by all men. All men shall become Catholics, and shall acknowledge the Pope as Vicar of Jesus Christ." (Some of the above may refer to the time of Antichrist.)

156a. Blessed Maria Taigi (d. 1837)

     "God will ordain two punishments: One, in the form of wars, revolutions and other evils, will originate on earth; the other will be sent from Heaven. There shall come over all the earth an intense darkness lasting three days and three nights. Nothing will be visible and the air will be laden with pestilence, which will claim principally but not exclusively the enemies of religion. During this darkness artificial light will be impossible. Only blessed candles can be lighted and will afford illumination. He who out of curiosity opens his window to look out or leaves his house will fall dead on the spot. During these three days the people should remain in their homes, pray the Rosary and beg God for mercy.
     "On this terrible occasion so many of these wicked men, enemies of His Church, and of their God, shall be killed by this divine scourge, that their corpses round Rome will be as numerous as the fish, which a recent inundation of the Tiber had carried into the city. All the enemies of the Church, secret as well as known, will perish over the whole earth during that universal darkness, with the exception of some few, whom God will soon after convert. The air shall be infected by demons, who will appear under all sorts of hideous forms.
     "After the three days of darkness, Saints Peter and Paul, having come down from heaven, will preach throughout the world and designate a new pope (see 150). A great light will flash from their bodies and will settle upon the cardinal, the future Pontiff. Then Christianity will spread throughout the world. Whole nations will join the Church shortly before the reign of Antichrist. These conversions will be amazing. Those who shall survive shall have to conduct themselves well. There shall be innumerable conversions of heretics, who will return to the bosom of the Church, all will note the edifying conduct of their lives, as well as that of all other Catholics. Russia, England, and China will come into the Church.

164. Abbess Maria Steiner (d. 1862)
     "I see the Lord as he will be scourging the world, and chastising it in a fearful manner so that few men and women will remain. The monks will have to leave their monasteries, and the nuns will be driven from their convents, especially in Italy. . . . The Holy Church will be persecuted. . . . Unless people obtain pardon through their prayers, the time will come when they will see the sword and death, and Rome will be without a shepherd."
     "The Lord showed me how beautiful the world will be after the awful chastisement. The people will be like the Christians of the primitive Church."

168a. Ven. Magdalene Porzat (d. 1850)

     "An enormous bird (Great Monarch) shall awake as from a sleep, and with its terrible bill and claws shall sever the ox's neck and shall eagerly devour the intestines of the wicked dragon. He shall drag to the mud the tricolor (revolutionary) flag of the French and restore to their dominions the legitimate kings. A just and pious man born in Gallicia (Spain: Glory Of The Olives?) shall be the Supreme Pontiff; then the whole world shall be united and prosperous. One faith only and one emperor shall reign over the whole earth."

172a. Catherine Emmerich (d. 1824)

     "I wish the time were here when the Pope dressed in red will reign. I see the Apostles, not those of the past, but the apostles of the last times, and it seems to me, the Pope is among them."

173b. St. John Bosco (d. 1888)

"It was a dark night. Men could no longer tell which way to take in order to return to their homes. Of a sudden there appeared in the heavens a very bright light that illuminated the steps of the travellers as though it were midday. At that moment there was seen a host of men and women, of young and old, of nuns, monks and priests with the Holy Father at the head. They were going out from the Vatican and were arranging themselves in line for a procession.
     "Then there came a furious storm which clouded that light somewhat and made it appear that light and darkness were engaged in battle. In the meantime they arrived at a little square covered with dead and wounded, some of whom cried aloud and asked for help.
     "Very many were dropping out of the line of procession. After having walked for a time that would correspond to two hundred risings of the sun (200 days) they all realized that they were no longer in Rome. Struck with fear they all ran to the Holy Father to defend him personally and to attend his wants. Instantly two angels were seen carrying a banner, going they presented it to the Holy Father and said: 'Receive the banner of He Who fights and scatters the strongest armies of the world. Your enemies are dispersed. Your children with tears and sighs beg you to return.'
     "Looking at the banner one could see written on one side, 'Queen conceived without sin'; and on the other side, 'Help of Christians.'
     "The Holy Father joyfully took the banner, but looking closely at the small number of those who remained with him, he became very sad.
     "The two angels added: 'Go quickly to console your children. Write your brothers dispersed throughout the world that there must be a reform in the morals of men. That cannot be obtained except by distributing to the people the bread of the Divine Word. Catechize the children. Preach the detaching of the heart from the things that are of the earth. 'The time has come,' concluded the two angels, 'when the poor shall evangelize the people. Vocations will come from among those working with the spade, the axe, and the hammer to the end that they fulfill the words of David: God has raised up the poor from the land in order to place them on the thrones of the princes of His people.'
      "Having heard that, the Holy Father began the march. The farther he went the greater did the procession behind increase. When finally he set foot in the Holy City, he wept bitter tears for the distress in which he found the people and the large number now missing. As he entered St. Peter's he intoned the 'Te Deum' to which a choir of angels replied singing: 'Glory to God in the highest and on earth peace to men of good will.'
      "With the ending of the hymn there came an end to the thick darkness and the sun shone with a brightness all its own.
     "The cities, towns, and villages were thinly populated. The land had been leveled down as if by a hurricane, by a tempest, and a hail storm. People went from one to another saying in tones of great emotion: 'there is a God in Israel.'
     "From the beginning of the exile until the singing of the 'Te Deum,' the sun rose in the East two hundred times (200 days). The time that passed for the fulfilling of those things (all spoken of above) corresponds to four hundred risings of the sun."

179a. Pius X (d. 1914)

     "I saw one of my successors by name fleeing over the corpses of his brethren. He will flee to a place for a short respite where he is unknown, but he himself will die a cruel death."

201c.   Said to be Ancient Irish

"The close of the war finds a Celt in the Chair of Peter. He is the most perfect of all the popes; chosen miraculously amidst chaos. An angel in human form, he shall be called "Papa Angelorum." This Celt is not an Irish Celt but one born in Galicia, and the only Celt to occupy Peter's throne.
     "He shall, like Peter of old, take his staff and his scrip, and with a few companions start out to reconcile the nations. They shall walk over mounds of dead and find the rivers choked with the bodies of the dead. The pope will die in exile."
