Julius Firmicus Maternus was a Roman Latin writer and astrologer, who received a pagan classical education that made him conversant with Greek; he lived in the reign of Constantine I and his successors. His triple career made him a public advocate, an astrologer and finally a Christian apologist.
The explicit, or end-tag, of the sole surviving manuscript of his De errore profanarum religionum gives his name as Iulius Firmicus Maternus V C, identifying him as a vir clarissimus and a member of the senatorial class. He was also author of the most extensive surviving text of Roman astrology, Matheseos libri octo written around 334–337. Manuscripts of this work identify him as "the younger" (iunior) or "the Sicilian" (Siculus). The lunar crater Firmicus was named in his honour.
Julius Janonis was a Lithuanian poet and writer. Born to a family of poor peasants, he began writing and translating poems at the age of 14. Learning from Maironis, he wrote about nature and suffering of the poor. His first poems were published in 1912. While still a student, he began contributing articles to Lithuanian press and joined activities of leftist aušrininkai. He was a social-democrat but leaned more and more towards communism and his poetry became more and more political agitation. His views become even more radical when during World War I he evacuated to Voronezh and later Petrograd. He joined the Russian Social Democratic Labour Party (bolsheviks) and was imprisoned twice for revolutionary activities. He contracted tuberculosis and, unwilling to become a burden, committed suicide at age 21. In the Lithuanian SSR, Janonis was hailed as the "first poet of the proletariat".
