Jens Hendrik Oliver Djurhuus, called Janus Djurhuus, (26 February 1881, Tórshavn – 1 September 1948, Tórshavn) was the first modern Faroese poet. He and his younger brother Hans Andreas Djurhuus, also a poet, are called the Áarstova brothers after the house where they grew up.
Djurhuus' parents were Óla Jákup Djurhuus (1832–1909) and Else Marie née Poulsen, from Hósvík (1847–1897). He was a great-grandson of Jens Christian Djurhuus.
Djurhuus said that his "poetic baptism" came in school, when he heard Jákup Dahl (later a provost and Bible translator and author of the first school grammar of the Faroese language) declaim Jóannes Patursson's Nú er tann stundin komin til handa (Now is the hour come for acting), the anthem of the Christmas Meeting.
Djurhuus trained as a lawyer. After passing the preliminary examinations in 1897, he went to Denmark for university preparation, first in Copenhagen and then in Bornholm. He passed the qualifying examinations in 1900, graduated with the cand. jur. degree in 1911, and then practised in Copenhagen until the late 1930s, when he returned to the Faroes to practise there. However, he kept in touch with his homeland through students.
His first published poem was "Blíð er summarnátt á Føroya landi", in 1901. In 1914 he published Yrkingar (Poems), the first collection of a single poet's work published in Faroese. He published four further collections of poems.
Djurhuus had also studied classical philology, and also published accomplished Faroese translations of Ancient Greek and Latin works, including some of Plato's Dialogues and poetry by Sappho, and (posthumously) a poetic translation of the Iliad. (He also published translations of poetic works by Goethe, Dante, Heinrich Heine and Gustaf Fröding). There is a story that on one occasion when a Greek steamer called at Tórshavn, he went on board and sent a cabin boy for the captain. On his arrival, he began to recite the Odyssey in Ancient Greek. The astonished captain joined in.
