Notable poems, many of which were in collaboration with Ștefan Octavian Iosif, include Legenda funigeilor (dramatic poem, 1907), Cometa (comedy, 1908), Caleidoscopul lui A. Mirea (1908), Carmen saeculare (historical poem, 1909), published in 1910, Cireșul lui Lucullus (proză).

Around 1911 later in life he developed an interest in prose and published Povestea celor necăjiți (1911), Fantome (1911), Oglinda fermecată (1912), Triumful vieții (1912) and Steluța (1913).

He fell in love with Iosif's wife Natalia Negru, who left her husband and divorced him.

In the autumn of 1914, during a quarrel, Anghel fired a warning shot at Negru, lightly wounding her.

[2] Anghel was buried at Eternitatea Cemetery where at the funeral, an unknown female reportedly shouted, "You miserable woman, who kills all the country's great people!"
