Queen Elizabeth II, England’s longest reigning monarch, died on Sept. 8 at age 96.
She is now lying in state at Westminster Hall, and her coffin will remain there until the morning of her funeral on Monday.
Ahead of the queen’s funeral, female members of the royal family have been spotted wearing mourning veils as they attend various events in honor of the late queen.
A mourning veil is worn by someone who is grieving as a symbol of sorrow.
Unlike other religious head coverings, which typically sit atop the head and cascade down the hair, mourning veils also cover the face of the wearer, the BBC pointed out.
Most mourning veils are made of a dark-colored lace or netting and are nearly transparent.
In the case of Queen Elizabeth II, it is tradition for bereaved family members of the royal family to wear a mourning veil to a state funeral, the BBC noted.
Mourning veils, however, are not just limited to royalty.
First lady Jacqueline Kennedy famously wore a mourning veil during President John F. Kennedy’s funeral and funeral procession in Washington, D.C., in November 1963.
While female religious head coverings are commonly associated with brides, vowed religious sisters and followers of Islam or Orthodox Judaism, there is a longstanding tradition of everyday Christian women covering their heads during worship, according to the Gospel Coalition, a faith website.
Mourning veils have unique symbolism and meaning dating back to the Bible’s New Testament days, said Lily Wilson, owner of Veils by Lily in Kimmswick, Missouri.
Christian adherents to head coverings cite the Bible verse 1 Corinthians 11 as their reason for covering their heads, Wilson told Fox News Digital in a phone interview.
“In 1 Corinthians 11, the apostle Paul instructs the early church at Corinth that women should cover their heads when praying or prophesying,” she said.
“This instruction goes along with others meant to correct certain practices by the faithful during the early liturgy of the breaking of the bread, which was being carried out according to the command left by the Lord on the night before he died.”
Christian veiling largely fell out of practice “around the 1960s” among Catholic and mainline Protestant denominations, Wilson explained.
However, it has started to make a comeback.
“In recent years, some Christian women have returned to the practice, especially in conservative Catholic parishes and certain Christian denominations,” she said.
This includes the wearing of mourning veils at funerals.
“Customers who requested [mourning veils] appeared to be drawn to the privacy afforded by the lace that covered their faces,” Wilson said.
“In years past, moreso than today, it was seen as undesirable to show emotion in public.”
Mourning veils “served the dual purpose of giving privacy to the wearer in their mourning and covering the head according to the instructions of St. Paul in 1 Corinthians 11.”
The Rev. Jeffrey Kirby, pastor of Our Lady of Grace Parish in Indian Land, South Carolina, said in an email interview with Fox News Digital that the Bible teaches that “a women’s hair is her glory.”
When a woman was in public during biblical times, “she veiled her hair as a sign of modesty and, if married, as a sign of love and respect to her husband,” he said.
“Veils today can be worn, but they are not obligatory,” he added. “Some women who wear veils insist on other women wearing them, but Saint Paul’s counsel was limited to the Corinthians, perhaps because of a lack of morals [in Corinth].
“He did not ask for veils to be worn in other Christian communities. Today, when veils are ceremonially worn by women, it is a sign of esteem to the other person. When veils are worn at funerals, it is a traditional and uniquely feminine act of deference to the person who has died.”
For Wilson, veiling is “spiritually significant and enriching for our worship of God.”
An evening dress from the 1890s worn by “history’s most famous mourner,” Queen Victoria, was made of black taffeta and accompanied by a veil, according to the BBC.
While the mourning veil was sometimes described as a sort of armor, Jessica Regan, assistant curator at the Metropolitan Museum of Art in New York City, told the BBC “mourning dress was also a form of public display, viewed by some women as an outer expression of inner feelings.”
