You were also right that that quatrain does refer to Islam in relation to parts of southern Europe. Nostradamus was envisioning a repeat of the year 711 when the Moors invaded but this time including the Italian coastline as well.
Unsure how that quatrain is about the False Prophet though and I still find the Islamophobia and Christian conspiracy an unattractive feature of our society that harms more than helps. Thank you anyways for correcting me.
Please consider this verse.
Revelation 20:4 "And I saw thrones, and they sat upon them, and judgment was given unto them: and I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years."
Muhammad commanded his followers to strike off the heads of those who oppose Allah.
Islam is a great perpetrator of this act and even now in Europe, many are pushing for this type of punishment on anyone who rejects Islam.
Many claim the Antichrist will be a Muslim because of this, yet the Serpent is crafty in that it makes itself unseen to those who are in the World. Islam is too obvious of a following for many to target, which is why the AntiChrist will have his own Religion.
Yet the False Prophet must come from out of this following in order to fulfill God's word. Even in the Koran the False one is said to come from Mecca.
Please consider this.
