[3] D. Pedro Henrique de Bragança would be found countless times in his Library during his youth deeply interested in Philosophy and Geography in particular, although the Duke had a privileged education in all aspects of knowledge.
[4] D. Pedro was a man of a profoundly religious character, and the first place he visited when he arrived from his trips to his farms and villas outside the capital was the Confessionary.
[5] Although the Duke never married, he maintained a loving relationship with Luísa Clara de Portugal, the Myrtle Flower, which was not looked kindly upon by King D. João V. Eventually, after the intervention of Friar Gaspar da Encarnação, the King, godfather, and uncle to the Duke consented on the relationship, from which Ana de Bragança was born.
[6] Pedro Henrique de Bragança being one of the main candidates to the hand of D. Maria I - together with Prince Peter III of Portugal - all his vision for the rebuilding of the Palacio do Grilo was always linked to somewhat of a dream-like realm, a certain architectural fantasy of an oneiric kingdom, made partly real.
However, D. Pedro became fatally ill a few months after the massive 1755 Lisbon earthquake, presumably due to his tireless efforts to rebuild the city, having been regularly seen carrying shovels, hoes, and lifeless bodies.
