In recent decades, the history of Peru has been enriched by the results of the efficient work of archaeological projects that constantly surprise us with their discoveries. Archaeologists interpret cultural material in order to explain the use and function of objects, enclosures or temples, these interpretations being the ones that provide a better understanding of the historical legacy of the ancestors.

Andean man was always linked to the observation of natural phenomena, and to through it he could recognize his surroundings, and by recognizing them, understand them and then search them for their inherent attributes or powers. The wise men or leaders developed a social structure that became complex when collective thought transformed them into gods or deities, and they discovered tools to be able to interact with these forces. Thus, magic appears with the rite and societies were growing and interacting with each other:they exchanged food, objects and also ideologies; which were expressed in conventional images or symbols embodied in objects of various materials, thus allowing their ideas to be perpetuated in the group. The Lambayeque or Sicán culture developed in the middle valley of the La Leche River - Province of Ferreñafe, highlighted in architecture and dominated goldsmithing. It is in this activity that a very particular representation stands out, we refer to the well-known "Funeral Masks with Almond Eyes" which always accompany the deceased of high rank or importance. These masks are made of gold sheets painted red, with large almond-shaped eyes and some pieces have extensions in the form of eye stalks made of quartz or emerald beads, strung on thin tubes or wires. It has a small nose and mouth, it wears nose rings and nasal fringes, it also has circular earmuffs.

Its most outstanding features are: a smooth flattened carapace of red or orange color with white spots, face separated from the cap and slightly tilted forward, they have two pincers and eight ambulatory legs, their almond-shaped concavities stand out where their eye sockets are semi-transparent and exposed, which gives them an excellent 360° vision. If we make a physical comparison between the Lambayeque mask and the ghost crab, we observe that:both have transparent eye stalks that come out of almond-shaped cavities, they have a reddish coloration with two upper vertical lines, they have curved vertical grooves such as nasolabial furrows and hanging fringes on the below what could correspond to a nasal shape.


The mask in a ritual context has the capacity for communication and transformation of the individual who uses it, and unlike the theater, it is conceived as real. Therefore, if a character wears a condor mask, he will be the same incarnated condor and not just his representation, it is a mimetic transformation where the identity of the character is assumed and therefore the qualities and faculties are incorporated into the individual. of the being represented, in addition to protecting and hiding it. Considering this analysis, we could have a greater approximation and justification for the use of the "ghost crab" mask in Lambayeque rituals, since the crustacean is associated with death and it is very possible that when this mask was placed on the deceased, he acquired the faculties of the crustacean which allows it to move in the dark without problem, being the most outstanding being able to enter the underworld protected where apparently it would also be its natural environment. This crustacean was seen by the ancients as a being associated with death due to its scavenging and nocturnal activity, plus it naturally had the symbolic red color to be able to travel through the underworld, a color that coincidentally could also be associated with the moment the sun in the sunset (death of the sun) is appreciated reddish disappearing and that in an apparent perspective of his time, he would be starting his journey through the underworld to be reborn the next day in a new life.
