Margaret was born in 1242, the daughter of Bela IV, King of Hungary, and Maria Lascaris, daughter of the emperor of Constantinople. Before her birth her parents had vowed to dedicate their child to God if Hungary would be victorious over the invading Tartars. Their prayers were answered and so when almost four years old Margaret was placed in the Dominican monastery of Veszprim. At the age of twelve she moved to a new monastery built by her father near Buda and there made profession into the hands of Humbert of Romans. Margaret lived a life totally dedicated to Christ crucified and inspired her sisters by her asceticism, her works of mercy, her pursuit of peace, and her humble service. She had a special love for the Eucharist and the Passion of Christ and showed a special devotion to the Holy Spirit and Our Lady. She died on January 18, 1270.

  Leo left many doctrinal and spiritual writings behind and a number of them are included in the Office of Readings to this day. He died in 461.

  In the earliest centuries all vestments were white – the white of baptismal purity and of the robes worn by the armies of the redeemed in the Apocalypse, washed white in the blood of the Lamb. As the Church grew secure enough to be able to plan her liturgy, she began to use colour so that our sense of sight could deepen our experience of the mysteries of salvation, just as incense recruits our sense of smell and music that of hearing. Over the centuries various schemes of colour for feasts and seasons were worked out, and it is only as late as the 19th century that they were harmonized into their present form.
