The siren was painted by Sartorio following his first stay in London and is strongly influenced by the example of English Pre-Raphaelite painting. Back in Italy, the work was also reproduced on the "illustrated tribune", accompanied by some verses by Diego Angeli, and received the applause of contemporary critics. The composition with a deep horizontal cut is built around the figure of the sinuous mermaid with long red hair and diaphanous skin that surrounds the body of the young fisherman who leans out of the boat. The skulls, visible in transparency on the seabed behind the woman, suggest the end that awaits the young victim in the arms of the charmer. The mythological theme of the mermaid, usual in mythological painting, is addressed by Sartorio influenced by the Pre-Raphaelite and English symbolism that he had been able to study during his stay in London in 1893 - 1894.
