"And yet it moves" or "Albeit it does move" (Italian: E pur si muove or Eppur si muove [ep'pur si 'mw?:ve]) is a phrase attributed to the Italian mathematician, physicist and philosopher Galileo Galilei (1564-1642) in 1633 after being forced to recant his claims that the Earth moves around the immovable Sun rather than the converse during the Galileo affair.
In this context, the implication of the phrase is: despite his recantation, the Church's proclamations to the contrary, or any other conviction or doctrine of men, the Earth does, in fact, move (around the Sun, and not vice versa). As such, the phrase is used today as a sort of pithy retort implying that "it doesn't matter what you believe; these are the facts."

Overview
According to Stephen Hawking, some historians believe this episode might have happened upon Galileo's transfer from house arrest under the watch of Archbishop Ascanio Piccolomini to "another home, in the hills above Florence". This other home was also his own, the Villa Il Gioiello, in Arcetri.
The earliest biography of Galileo, written by his disciple Vincenzo Viviani in 1655-1656, does not mention this phrase, and records of his trial do not cite it. Some authors say it would have been imprudent for Galileo to have said such a thing before the Inquisition.
In 1911, the words "E pur si muove" were found on a Spanish painting which had just been acquired by an art collector, Jules van Belle, of Roeselare, Belgium. This painting was completed within a year or two of Galileo's death, as it is dated 1643 or 1645 (the last digit is partially obscured). The painting is not historically correct, because it depicts Galileo in a dungeon, but nonetheless shows that some variant of the "Eppur si muove" anecdote was in circulation immediately after his death, when many who had known him were still alive to attest to it, and that it had been circulating for over a century before it was published.
The event was first reported in English print in 1757 by Giuseppe Baretti in his book The Italian Library:
The moment he was set at liberty, he looked up to the sky and down to the ground, and, stamping with his foot, in a contemplative mood, said, Eppur si muove, that is, still it moves, meaning the Earth.
The book was written 124 years after the supposed utterance and became widely published in Querelles Littéraires in 1761.
