; c. 1540s. She was a renowned beauty of a pale complexion and clear blue eyes. Maria de Avíz was born on 18 June 1521, in
Lisbon,
Portugal. She was the only daughter of King
Manuel I of Portugal and Infanta
Eleanor of Austria. Five months after her birth, her father died of the plague and was succeeded by her half-brother,
John III of Portugal. Shortly afterwards, in May 1523, her mother departed to Spain, leaving Maria to be raised in Portugal at her half-brother's court. In 1525 her maternal aunt,
Catherine of Austria, married John III of Portugal. The Queen took care of the upbringing and education of Maria, who was loved like one of her own daughters. Maria's education was astounding for a woman of her time since her teachers included female scholars, such as humanists
Joana Vaz,
Luisa Sigeia, and
Públia Hortênsia de Castro. Lessons included
finances,
architecture,
literature, and several languages. One of the most educated of the Portuguese infantas, Maria became a famed humanist and protector of the arts. Her household was made into an intellectual circle that welcomed women of letters. It was rumored that she fell in love with Portugal's greatest poet,
Luís de Camões. Although she did not lack suitors and had several marriage proposals, Maria never married. Her engagement with
Dauphin Francis was negotiated with the support of her mother Eleanor, but the prince died in 1536. After his death, Eleanor tried to arrange a marriage between Maria and the Dauphin's younger brother,
Charles II of Orléans, in hopes that the prospective match would enable Maria to join her at the French court. Despite Eleanor's endeavors, the marriage did not materialize because Charles V and John III did not like the idea of Maria's immense wealth being at the disposal of France. In 1537, Maria and her cousin
Christina, Dowager Duchess of Milan, were briefly considered as possible brides for
Henry VIII of England. However, England soon dropped any pursuit. Maria was considered as a second wife for her
cousin and half-nephew, the future
Philip II of Spain, son of her uncle,
Emperor Charles V, and her half-sister
Isabella. The matter was taken under serious consideration from 1549 onward, when her mother settled in
Brussels, but these plans were discontinued when
Mary Tudor succeeded to the English throne in 1553 and Charles V decided to marry his son Philip to a monarch. Other candidates for her hand were Archduke
Maximilian of Austria; his father
Ferdinand I, Holy Roman Emperor;
James V of Scotland; and the
Duke of Savoy. ==Duchess of Viseu==
