Summary from Wikipedia

He focused on dodecasyllable and hendecasyllable verse, which allowed him to achieve beautiful rhythm and rhyme in his poems. He was quite a perfectionist and therefore only published three collections of poems (1903, 1912, 1924). He wrote largely about death and non-existence, keeping the tone sceptical and ironic. Some of his most well-known poems are An Honest Song (Iskrena pesma), A Desperate Song (Očajna pesma), Jefimija, Simonida and At Gazi-Mestan (Na Gazi-Mestanu). He was a member of the Serbian Royal Academy (1934).[2]
