In November 1888, Moderno founded the magazine
Recreio das Salas (Recreation of the Salon) which published works from Portuguese literary figures. She continued to publish her own works in the
Almanaque, such as the poems,
Dois sóis (Two suns) and
Adeus! (Goodbye!). In 1889, she began to work as a journalist for the
Diário de Anúncios (Advertising Diary), and serialized her first novel,
Dr. Luís Sandoval within its pages. By 1892, she was directing the
Diário and editing the novel to be published as a book. That same year, she began a courtship by correspondence with the intellectual, Joaquim de Araújo, but made it very clear to him that she was not an adherent to the
Victorian values of women's domesticity. She explained that she taught 20 students and when she was not teaching, she was writing and was completely uninterested in sewing or domestic activity, having hired someone to do those tasks. The relationship flourished through romantic letters, but when de Araújo came in 1893 to Ponta Delgada and the couple met for the first time, they realized that the relationship would never progress. Moderno published
Os mártires do amor (The Martyrs of Love) in 1894, dedicating it to de Araújo and then broke off their relationship. Around this time, in 1893 Moderno's father moved to the United States, leaving debts behind. Her literary output declined as she had to work to pay off his obligations and she moved into the home of a friend, Maria Emília Borges de Medeiros. In 1901, she produced
Açores, pessoas e coisas (Azores, people and things) and the following year founded the journal
A Folha (The Leaf), which she published among other items from the business
Tipografia A. Moderno. In 1904, returned to the
Almanaque, publishing the sonnet
Camões to the memory of the poet,
Luís de Camões. Moderno and Borges opened their home in 1906 to
Maria Evelina de Sousa, a fellow teacher and writer. Sousa and Moderno lived openly as
lesbians, though after their deaths, biographers focused on Moderno's heterosexual long-distance relationship with de Araújo. In addition to her writing, Moderno ran a variety of businesses. In 1907, she purchased a bookstore and sold international volumes. Two years later, she purchased a pineapple farm in
Fajã de Baixo, where she grew produce to export to the United States. She also served as an insurance agent for several national and international commercial enterprises. In 1908, Moderno and Sousa created the first animal welfare organization in the Azores, establishing the Micaelense Society for the Protection of Animals (). She favored the establishment of the
Portuguese Republic and supported the
coup d'état which replaced the monarchy. In the constitutional discussions that followed, she contributed numerous articles in favor of divorce to protect women, advocated for women's education and pressed for women's rights. She joined the Republican League of Portuguese Women and participated in many activities of the association. In August 1912, while on a visit in
Lisbon, de Sousa and Moderno were honored by the Republican League for their efforts in being the primary agitators for women's rights and education in the Azores Moderno edited the journal
Revista Pedagógica (Pedagogical Magazine) founded by Sousa and Sousa worked on the editorial staff of Folha. Throughout the 1940s, the couple were often seen walking their dog around Ponta Delgada, with Moderno dressed in men's attire using a walking stick and smoking a cigar. ==Death and legacy==
