Diu Lei is not only proficient in various painting techniques, but also has a rich imagination, which is indispensable as an artist. From his works, we can see that his art not only has the characteristics of Dutch delicacy and individuality, but also has the characteristics of southern European art, as well as the beauty, idealization and scientificity of southern European art. He is the first artist to try to integrate the two arts. Diu Lei is also very good at woodcut and copperplate, and promoted the status of printmaking as a religious illustration to the status of artistic independent painting.
Diu Lei's important works include Bronze Edition Melancholy, Woodcut Four Horsemen of Revelation and Oil Painting Four Apostles.
"Melancholy" in the copperplate painting depicts an archangel with strong physique and wings. With his head in one hand and a compass symbolizing science in the other, he was deeply lost in thought. It symbolizes artistic exploration based on scientific research or philosophical meditation on the new era.
The woodcut Four Horsemen of Revelation shows that when the end comes, four horsemen (representing war, plague, poverty and death respectively) fall from the sky to judge mankind. The painter's description of details is very meticulous, and his works are rich and substantial.
The oil painting Four Apostles is one of Diu Lei's most famous works. There are four saints in the long and narrow vertical composition, representing kindness and justice respectively. The picture is compact in composition, three-dimensional, and the four apostles are tall and verve, which embodies the distinct humanistic thought.
