Jan Olis was born in Gorinchem. One of his pictures is signed from Rome in 1631, so it is presumed that he visited Italy at this time. He worked in Dordrecht and later in Heusden. He is referred to at various times as an alderman (of Heusden), a burgomaster, a vintner and a tax-collector.
There are few works by him; most are festive
genre scenes. He may have given up painting in his later years.
