His major works include historical topics, portraits, and scenes of everyday life.
One of his most famous paintings is “The Poets”, which depicts some of the most important representatives of the New Athenian school of poetry, also known as the Generation of 1880.
[1][2] Born in Stemnitsa, Roilos began his studies at the School of Fine Arts in Athens from 1880 to 1887.
He was among the first to introduce impressionism into Greek painting, thus subverting the academic style of the "Munich School".
He was a teacher and early mentor of, among others, Giorgio de Chirico, who, in his memoirs, commends the outstanding quality of Roilos's painting, which he deems superior to that of Giovanni Fattori.
