The stone was rolled back (Mk 16:4-16:4)

“When they looked up,

They saw

That the stone,

Which was very large,

Had already

Been rolled back.”

 

καὶ ἀναβλέψασαι θεωροῦσιν ὅτι ἀνακεκύλισται ὁ λίθος· ἦν γὰρ μέγας σφόδρα.

 

However, just like in the other gospel stories, Luke, chapter 24:2, and John, chapter 20:1, the stone had been removed when they got there.  Matthew, chapter 28:2, had the women watch as an earthquake and an angel rolled back the stone at the entrance to the tomb.  Mark said that when the 3 women looked up (καὶ ἀναβλέψασαι), they saw (θεωροῦσιν) that the stone had already been rolled away (ὅτι ἀνακεκύλισται ὁ λίθος), even though it was very large (ἦν γὰρ μέγας σφόδρα).  Thus, that was another problem solved.
