Note 79 — Chapter III
Reading edition
In fact the Cortes of Aragon obstinately refused to swear allegiance to the Infanta Isabel as heiress when she went to Saragossa for the purpose in the autumn; and she was kept there in great distress until her expected child should be born, which, if it were a male, would receive the oath of the Cortes. The anxiety and worry consequent upon this killed the Infanta (Queen of Portugal) in the birth of her child Miguel in August.
