I want to know the answer to the following question:
What institution holds a heel bone with a spike inserted?
All the background I'm provided with is that "Although almost all ancient sources relating to crucifixion are literary, the 1968 archeological discovery just northeast of Jerusalem of the body of a crucified man dated to the 1st century provided good confirmatory evidence that crucifixions occurred during the Roman period roughly according to the manner in which the crucifixion of Jesus is described in the gospels.". Is that enough to answer the question?
Answer: no
