“Though Mary had smiled as she announced her namesake’s pregnancy at court, behind closed doors was a different matter altogether. Her brother now expected an heir before her, and if god forbid the Duchess gave birth to a son, uprisings from the Evangelicals who wanted her removed from the throne were sure to follow. The pressure for her to wed and produce an heir was mounting, and there is evidence that it had affected Mary’s psyche. Now housed in the Royal Museum, the queen’s prayer book survives, its pages worn and stained, purportedly from her tears as she prayed for guidance and an heir to rule after her [1].”
– Rosalind Sharpe, This Fair Marigold: A Comprehensive Analysis of Mary I’s Reign
“Easter gifts to the queen doubled as courtship gifts, The Countess of Salisbury, on behalf of her son, sent her former charge a Book of Hours, famous even in the present day for prominently featuring a lioness devouring a falcon in its maw, an obvious jab at the Marquess of Pembroke who had owned a choir book bearing an illustration of a falcon pecking at a pomegranate [2]. Not to be outdone, the Queen of Scots sent over to her niece a jewelled cross, studded with precious stones, and a note that stated that it was part of her dowry as an heirloom from Elizabeth of York [3].
From the continent, too, arrived gifts for the highly eligible queen. The Emperor had sent over a massive oaken chest, evocative of an Italian cassone, which bore on the underside of its lid a carving of the late queen’s symbol, that of a crowned pomegranate impaled with the Tudor rose. Inside were rolls of damask and Flemish cloth from the Empress, as well as the portraits of her brothers, the Portuguese infantes Luis and Duarte, who had also sent over their own gifts. From Luis, Mary had received a pomander ball shaped as a pomegranate, studded with rubies and set with a clock on its centre. Duarte, for his part, had sent the Queen a fine goblet of gold decorated with pearls.
France, on the other hand, had sent over for the Queen’s inspection their chiefest jewel, for the Dauphin had landed with his retinue upon English soil that Easter Monday and was now on the road, arriving at the court in Windsor a day after the Duchess of Richmond’s pregnancy was announced.”

This was actually a thing, by the way, except historians think it happened during Mary's false pregnancy IOTL.

Anne Boleyn did have a choir book with that exact illustration, most likely dating during the Great Matter as the falcon was not crowned.

this portrait, if anyone's curious.
