This prediction of the end-time flood of Ireland is often associated with another prophecy attributed to St. Colmcille (who is also known by his Latin name St. Columba).
I concede a favour to them without exception,
and St Patrick also did concede the same;
that seven years before the last day,
the sea shall submerge Eirin by one inundation
The above prophecy is believed to be taken from a 9th century document titled Colum Cille cecinit , but so far the earliest source it can be traced back to is O’Kearney, N. The Prophecies of Ss. Columbkille, Maeltamlacht, Ultan, Seadhna, Coireall, Bearcan, Malachy, &tc (Dublin: John O’Daly, 1856) – a book which is known to contain many spurious prophecies formulated as rhetoric for the 1798 Irish rebellion. It is possible that this quatrain is based on an earlier source or tradition, such as the Leabhar Breac , but currently its origins remains untraceable. It is unlikely that the original prophecy was made by St. Colmcille, but instead may have developed from the earlier, almost certainly authentic literature concerning the life of St. Patrick.
The prophecy of Ireland being destroyed by end-time floods is intimately related to the other material in Public and private revelation which tells of an eschatological inundation, and seems to be inextricably linked to the threat posed by the collapse of the volcano Cumbre Vieja into the Atlantic ocean (see the earlier post Mega-tsunami, where I show how this event is connected with the “great mounatin, burning with fire” being thrown into the sea in Rev 8:8, as well as several other biblical passages).
As we can see from the diagram below, Ireland is one of the countries that would be most affected be a mega-tsunami generated by the collapse of the volcano Cumbre Vieja in the Canary Islands.
This would lead us to ask why Ireland seems to be the sole focus of the prophecy of St. Patrick? Why would when there are so many other countries in even greater risk from this catastrophe. One explanation may be found in the fact that this prediction was made almost one thousand years before the discovery of America by the Europeans. The other countries which will be affected by this disaster would simply have been unknown to the saint.
According to Christian prophetic tradition, the tribulation period at the end-time (which includes the reign of the Antichrist) will last for a total of seven years. The fact that the prophecy of St. Patrick foretells that Ireland would be destroyed by the sea seven years before the last day in order to spare the Irish from the reign of the Antichrist therefore suggests that the rule of this end-time tyrant will only take place after the catastrophic flooding caused by the collapse of the volcano Cumbre Vieja into the sea. http://unveilingtheapocalypse.blogspot.com/2011/10/st-patrick-and-end-time-flood-of.html
