The Hermandad de la Santa Caridad was an institution that has origins in 1456, and dedicated to collecting drowned corpses and burying the poor and executed, and was among others that were born due to the Counter-Reformation, Seville transforming into a sort of convent-city by 1671 with 45 friar monasteries and 28 female convents.
[4] You can separate the artwork into three main planes, in the first you can observe two corpses arranged in coffins, the first is a skeleton dressed in religious garb, surrounded by insects walking across it, and the second is a man covered by a cloak.
The soldiers of the Order of Calatrava probably had positive connotations to the artist, for example bravery and courage which is demonstrated by its historic origin, expelling Muslims from Christian territory.
In the second plane on the top, you can observe an allusion to the judgement of souls normally represented by Saint Michael the Archangel holding a balance, in this case it's the hand of Christ, surrounded by clouds and the golden halo which illuminates them.
The elements in the artwork show a moral message to those who see it, and it fulfils the purpose of the Counter-Reformation to make clear that salvation can be achieved by human actions and through joining the church.
