I just found Kupka from looking at Orphic Cubism of which he was a co-founder and his work makes my eyes want to vomit with joy, like his stuff is so good it makes me furiously happy, which is what seems to happen when I find Eastern European artists that I really like.
Kupka was born in Austria-Hungary 1871, studied in Prague, he painted historical and patriotic themes at this time, afterwards he studied in Vienna where he focused on symbolic and allegorical subjects. He was influenced by the lifestyle of Karl Diefenbach and in 1894 Eastern philosophy became involved in him.
Kupka served as a volunteer in WW1 and was 25 years older than all the other soldiers. Serving with Blaise Cendrars he is mentioned in Le Main Coupée. He left the front due to frostbite of the foot.
Working as an illustrator in Paris where he settled from 1894, he became known for satirical drawings in newspapers and magazines.
He was deeply impressed by the Futurist Manifesto in 1909 and so painted The Piano Keys/Lake (img 2) that same year marking the beginning of his abstract representational style which increased in his work during 1910-1911 in which reflected his theories in motion, colour, and the relationship between music and painting (Orphism).
And his studies go on including completing a book; Creation in the Plastic Arts published in 1923, exhibited widely with the Cubist and other Abstract Art/ists.
