In Greek mythology, Sirens are sea monsters with the upper body of a woman and the lower body of a bird, and are known for their captivating nature. They are said to live on rocky islands and lure sailors with their beautiful singing, causing their ships to crash into the rocks and sink. In this work, Sirens and their eggs, depicted in a unique form by Klee, are shown drawing sailors near while singing from these rocks. The rounded, curved depictions seen in Klee’s later years appear to trace the process of lines gently connecting in motion. Similar forms can be observed in a series of drawings created in the same year as this work, in 1939. The gray and red eggs produced by the Sirens singing with their mouths wide open evoke the creation of the cosmos and the beginning of all things through the cycle of birth and death. This seems to be connected to the fact that Sirens were symbols of “death” and the “unknown” in ancient Greece.
