Is the 'rock' an allusion to Simon Peter (Πετρος) ?Then Joseph bought some linen cloth. He took down the body and wrapped it in the linen. He put it in a tomb cut out of rock (ἐκ πέτρας). Then he rolled a stone against the entrance to the tomb.
If the answer is yes, then the allegorical meaning would be that the Word (Jesus) is buried ''in'' Peter (the rock) and the disciples but even so the Word disappears from there (the empty tomb) and rises in Galilee of gentiles, where Peter is unable to arrive since the women don't tell nothing about what they have seen and listened.
But the silence of the women may be interpreted in this way, too:
they dont' say that the tomb cut “out of rock” (out of 'Peter') is empty, therefore, by their silence, they are false witnesses and false disciples. Jesus has abandoned DE FACTO Peter both materially and spiritually and the fact is not declared openly by the women.
Hence who proclaims that Peter is an apostle at the time of 'Mark' is a liar and a heretic Christian.
