Paul Mogensen (born 1941) had his first one-person exhibition at the Bykert Gallery, New York, in March 1967. A pioneering minimalist painter, Mogensen worked then—as now—on paintings guided by such ancient mathematical rules as the golden ratio. In early 1968, Mogensen boarded a rivet-plated British passenger ship in Madras (now Chennai), India, which traveled for six days to Penang Island, Malaya, off the west coast of Malaysia. He carried with him a children's notebook in which he drew a few ideas related to what he was seeing on his travels and worked on the arithmetic that continues to inform his paintings. Paul Mogensen: Early 1968 is a facsimile of the workbook from that time. An intimate volume, offering a glimpse of how Mogensen worked out his mathematical imagery in relation to the outside world, this publication is the only book available on this key minimalist artist.
