 Charles never recovered from Isabella's death, dressing in black for the rest of his life to show his eternal mourning, and, unlike most kings of the time, he never remarried.In memory of his wife, the Emperor commissioned the painter Titian to paint several posthumous portraits of Isabella; the finished portraits included Titian's "Portrait of Empress Isabel of Portugal" and "La Gloria".Charles kept these paintings with him whenever he travelled, and they were among those that he brought with him after his retirement to the Monastery of Yuste in 1557.
