María del Pilar Sinués y Navarro de Marco (19 December 1835, Zaragoza, Aragon - 20 November 1893, Madrid), was a popular and prolific 19th-century Spanish writer of various genres including novels, poetry, and informative works.

[8] In 1856, she married by proxy the Valencian journalist and comedian José Marco y Sanchís (1830-1895),[9] whom she only knew from letters due to their mutual admiration for her works.

Sinues directed her weekly magazine El ángel del hogar (The angel of the home) between 1864 and 1869, a publication on literature, theater, fashion, and work.

[10] This caused her to be criticized for her prolixity; in the satirical magazine El Moro Muza, a parody of her was made about an anecdote that she would collect and about which she would put together a novel.

[11] She published regularly in the progressive newspaper El impartial with topics related to the female question such as education, the possibility of working, morality, and religion.6[13] In 1883, she launched the first issue of Flores y Perlas, directed by her and written only by women, but nothing further is recorded about the continuity of the magazine.

[10] The discredit into which the figure of Sinués fell was due to the devaluation of Elizabethan culture by considering Sinues feminine and far from the male creative genius, the dominant concept in the Restoration.

[13] In her works, she designed the model of the woman of her time: good daughters, with a suitable husband; mothers, responsible for the education of their children, and with an eye to the general happiness of their family.

Sinués obtained her great literary success because she adhered to the "Elizabethan canon" that associated aesthetic beauty with works of Christian inspiration and moralizing.

The undisputed influence came from the theoretical works of the French poet Alphonse de Lamartine on Christian idealism that endorsed women's literature of sentimental, religious, domestic, and landscape themes, where Sinués came in.

Later, she wrote costumbrist works in the style of Böhl de Faber, and in the moralist and educational El ángel del hogar, Sinues will enumerate how a virtuous writer who is also a daughter, sister, mother, and wife should be; her private life must be blameless.

[11] When she moved to Madrid, she expanded her literary work by writing manuals of conduct for the Christian family, bulletins, and translations of French novels.

Also between 1864 and 1869, she wrote a nine-volume Galería de mujeres célebres (Gallery of Famous Women), which includes female trajectories far from "the angel of the home".
