Says Alexander Hislop regarding the festival of Easter:
Easter is nothing else than Astarte, one of the titles of Beltis, the queen of heaven, whose name, as pronounced by the people of Nineveh, was evidently identical with that now in common use in this country. That name, as found by Layard on the Assyrian monuments, is Ishtar (The Two Babylons, p. 103).
Cassianus, the monk of Marseilles, writing in the fifth century, and contrasting the primitive Church with the Church in his day, The forty days' abstinence of Lent was directly borrowed from the worshippers of the Babylonian goddess. Such a Lent of forty days, "in the spring of the year," is still observed by the Yezidis or Pagan Devil-worshippers of Koordistan, who have inherited it from their early masters, the Babylonians.
In the Mystery religion of Babylon, the false savior Tammuz was worshipped with various spring rites. Through the weeping of his mother Easter, or Semiramis, he was mystically revived, his resurrection symbolized by the budding of new vegetation in the spring. Each year the pagan spring festival celebrated this resurrection story.
In Ezekiel chapter 8 we saw women weeping for Tammuz, and the very next abomination was men in the temple of YEHOVAH God worshipping toward the rising sun! Ezekiel was speaking of this same ancient pagan celebration of the weeping for Tammuz, and the observance of this pagan spring festival.
