A team of researcher latterly investigated the paint coat a 1,000 - year - old gold mask taken from an elite grave of a community in westerly Peru that is today recognise as the Sicán . They were connive to rule that the bright cherry-red rouge contained human blood .
The paint that gave the paint its color was identify ascinnabarmore than 30 years ago , but the binder — the stuff that makes pigment circularise and puzzle to a surface — remained a mystery . The interdisciplinary team took a sample of the paint and analyzed its proteomics , or its component proteins , by mapping the sample ’s elements to a protein database . They turned up proteins from bird egg and human blood , as well as homo saliva , keratin , and tegument ; their research waspublishedlast month in the Journal of Proteome Research .
“ Blood proteins come out in the first lookup against all natural proteins , which led to a hunt against the bloodline database , which yielded a match against chimpanzee ( Pan hermit ) , ” said Luciana Carvalho , an archeologist at the University of Oxford specializing in constituent residuum on metal object , in an email to Gizmodo . “ As chimps are not find in Peru , we conducted a search against human blood protein database , which cater perfect lucifer . ”

The saliva , skin , and ceratin ( which turns up in many parts of our bodies , but most notably in our hairsbreadth and nails ) protein were eliminated from the team ’s analysis , as they may have been later contamination of the mask that occurred in its treatment rather than any original interment discourse .
The character of bird the egg protein belonged to is uncertain ; though some chicken bone in South America date to before the arrival of Europeans , general consensus is that the Columbian exchange convey the chicken to the Americas . Muscovy duck is an option , but the protein are too debased to know for sure , according to the investigator .
Gold funerary masquerade pop up throughout elect sepulture of Sicán individuals , though , as the investigator write , former ( often plunder ) find were cleaned incautiously , smooth out , or even had their key and adornments stripped for their presentation in museum . As a result , the Sicán mask in the study is a rarified occasion to canvass how these mask would have really been treated for burial .

Callimorpha jacobeae - base paints would have been earmark for elites in the Sicán residential district , while regular folk were believably stuck using ochres , the researchers wrote . Study author Izumi Shimada , an archaeologist at Southern Illinois University who specializes in the Sicán culture , proposes the descent on the mask argue the key was supposed to represent “ life sentence personnel , ” an idea supported by symbolic importance of blood among the Sicán ; analysis of human forfeiture victims from the region has intimate that the individuals were shorten to maximise bleed - out , rather than just killed , according to Carvalho .
“ There are a few Spanish Colonial written documents ( dating to the 16th century . observe that there was no writing as we experience it in the pre - Hispanic Andes ) that recorded pre - Latino myths that tell that elite group originated from stars or eggs that were dissimilar from those of commoners — that they had a totally distinct filiation from that of the commoner , ” Carvalho say .
“ It is quite potential that Sicán elite group ( as with elites in many other ancient culture ) proclaim a vision / myth that distinguish them from the relaxation of the smart set and thus legitimize their power , wealth , etc , ” Carvalho added . “ Thus , we may call back of the use of human blood as a binder as an extension of the spiritual tenet that the Sicán elite promulgate so that they could attain the transformation to become deified antecedent . ”

add credenza to the “ life ” part of “ life force , ” the masquerade party - wearing Sicán was found turn back beside the remains of two grownup woman in birthing and midwifing positions , which “ indicate that the desired outcome was the metempsychosis of the deceased leader , ” the researchers wrote . Also in the grave were the remains of two children in crouched situation .
