Meaning of "Sardonicus" by UB40

The character of Sardonicus in the lyrics may represent someone who appears pleasant and friendly on the surface, but conceals a darker, manipulative side underneath. The reference to a "hidden glint of madness" suggests a sinister aspect to his personality that is not immediately apparent. The portrayal of Sardonicus as a paradox etched in human bone speaks to the complexity of human nature and the capacity for duplicity that exists within individuals. The warning that many men are fooled by his smile serves as a cautionary tale about not judging people solely based on appearances and superficial charm. Ultimately, the lyrics convey a sense of suspicion and wariness towards those who may seem too good to be true, urging listeners to look beyond the façade and trust their instincts.
