“When they looked up,
That the stone,
Which was very large,
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.
