On the 15th February 1554, 3 days after Jane’s execution, the author of ‘The Accession, Coronation and Marriage of Mary Tudor’ wrote that
‘the same day towards 9 a.m. many people noticed in the clear sky two suns with one huge iris: If it is allowed to take it as a good omen, who can prevent us from interpreting it as the foreboding of the union of the two greatest Kingdoms of Spain and England?’ p.73
