Various explanations have been offered to account for the variance of colour. White has been supposed to denote purity--and to this day white gloves and hatbands and scarves are employed at the funeral of a young girl.
Yellow has been supposed to symbolise that death is the end of human hopes, because falling leaves are sere; black is taken as the privation of light; and purple or violet also affected as a blending of joy with sorrow. Christian moralists have declaimed against black as heathen, as denoting an aspect of death devoid of hope, and gradually purple is taking its place in the trappings of the hearse, if not of the mourners, and the pall is now very generally violet.
But these explanations are after-thoughts, and an attempt to give reason for the divergence of usage which might satisfy: they are really no explanations at all. The usage goes back to a period when there were no such refinements of thought. If violet or purple has been traditional, it is so merely because the ancestral Briton stained himself with woad on the death of a relative.
The pipe-clay, lampblack, yellow ochre, and woad of the primeval mourners must be brought into range with a whole series of other mourning usages, and then the result is something of an "eye-opener." It reveals a condition of mind and an aspect of death that cause not a little surprise and amusement. It is one of the most astonishing, and, perhaps, shocking traits of barbarous life, that death revolutionises completely the feelings of the survivors towards their deceased husbands, wives, parents, and other relatives.
A married couple may have been sincerely attached to each other so long as the vital spark was twinkling, but the moment it is extinguished the dead partner becomes, not a sadly sweet reminiscence, but an object of the liveliest terror to the survivor. He or she does everything that ingenuity can suggest to get himself or herself out of all association in body and spirit with the late lamented. Death is held to be thoroughly demoralising to the deceased. However exemplary a person he or she may have been in life, after death the ghost is little less than a plaguing, spiteful spirit.
There is in the savage no tender clinging to the remembrance of the loved one; he is transformed into a terrible bugbear, who must be evaded and avoided by every contrivance conceivable. This is due, doubtless, mainly to the inability of the uncultivated mind to discriminate between what is seen waking from what presents itself in phantasy to the dreaming head. After a funeral it is natural enough for the mourners to dream of the dead, and they at once conclude that they have been visited by his _revenant_. After a funeral feast--a great gorging of pork or beef--it is very natural that the sense of oppression and pain felt should be associated with the dear departed, and should translate itself into the idea that he has come from his grave to sit on the chests of those who have bewailed him.
