The Gospel accounts of the resurrection of Jesus are sometimes thought to be hopelessly inconsistent with each other.  Thus, their historical accuracy is doubted.

One profitable line of enquiry is to how the various account line up with what is know about burial practices in the 1st century.

Ian Paul gives a few examples:-

‘Only the family tombs of the relatively wealthy would have disk-like round stones closing the entrance which need to be rolled away (and there are more and more examples of these being excavated year by year); the entrances are often quite low, so you would indeed need to stoop down to see the inside (John 20.5) and the space (unlike a modern ‘tomb’) can indeed be ‘entered’ (Mark 16.5).
