#melancholic delusion

• Abenceragi — A historical and cultural eponym derived from the name of the noble Moorish Abencerrages lineage of Granada, sporadically used in 19th-century classical psychiatric literature and psychoanalytic analyses (the Abenceragi syndrome or complex). In old alienism semiology, the term described a specific variant of melancholic delusion mixed with ideas of lost family pride, chronic resentment, and paranoid suspicion of plotted betrayal. It characterizes patients exhibiting an obsessive monomania centered on the symbolic revenge of a clan's honor or on experiencing a morbid, destructive nostalgia for an idealized glorious past.
