The standard of Her Holiness, Leona X, Abbess of Massilia and Matriarch of the West.
Known in antiquity as "Massilia", the city of Marseille on the French coast is home to the Matriarchate of Massilia, founded by the disciple Mary of Magdala, alongside her siblings, Martha Lazarus of Bethany (the Bishop of Massilia), after their ministry in the Roman province of... Provence. After her death, the apostolic succession was established in the city - only females could become Matriarchs, and were elected in the same manner as the Patriarchs of the Pentarchy.
The jar of ointment was brought by Mary Magdalene to Jesus’ tomb to anoint his dead body. The skull represents her presence at Golgotha, “The Place of the Skull”. (Her actual skull is kept in St. Maximin, France.) Both of these symbols are commonly shown beside Mary in classical art.
The nun’s habit has been worn by every Matriarch of Massilia since – supposedly – the reign of Magdalene herself. The seven fleur-de-lis represent the seven demons driven out of her body by Jesus Christ.EDIT:
