The discovery of Richard III’s remains in Leicester marks a significant moment for both Historians and Archaeologists in this country. The fact that the remains of the king were situated in Leicester is not what is significant, although the ignominy of an English King being buried ungraciously under a car park does make for an anecdotal footnote at the very least.
What is of significance here is the subsequent facial reconstruction and the analysis of his skeletal structure, because now there is proof (up to a point) that paintings and descriptions of the last Plantagenet King of England were accurate. No longer do we have to rely purely on Royal portraits and Shakespearean descriptions, whose veracity has always been rather dubious: instead we have proof positive that Richard III was almost identical to how he was officially portrayed.
This has massive implications for other royal portraits; we can have more faith in the accuracy of portraits at this time, which is pertinent in the realm of primary sources; the doubts about their accuracy are significantly lessened.
