 The Latin reference to "Argentinus medicus", was originally translated as "a Strasbourg doctor"; however, D.E.Rhodes suggests it may actually refer to "Doctor Argentine", whom Rhodes identifies as John Argentine, an English physician who would later serve as provost of King's College, Cambridge, and as doctor to Arthur, Prince of Wales, eldest son of King Henry VII of England (Henry Tudor).There are reports of the two princes being seen playing in the tower grounds shortly after Richard joined his brother, but there are no recorded sightings of either of them after the summer of 1483.
