S. Scholastica (480-543) was of Roman nobility, the twin sister of S. Benedict. Her mother died in childbirth. She dedicated her life to God, becoming a nun at an early age. Pope Saint Gregory tells some of the stories of her life, including how she prayed for a thunderstorm one evening, so that her brother would stay with her all night discussing theological matters. Also how when she died, her brother saw her soul flying to heaven in the form of a dove. She is the patron saint against rain and storms. Represented as a nun with crozier and crucifix, or with a dove. Feast February 10.
S. Ursula is a legendary princess, the daughter of a Christian British king. She travelled Europe in company of either 11 or 11,000 fellow maidens. It is believed that the 11,000 number resulted from the mistake of a copyist who thought that the M (= Martyrs) in 11M was a roman numeral. Ursula and her companions were tortured to death to get them to renounce their faith. The Ursuline Order, founded for the education of young Catholic girls and women, is named after her. Represented with arrows, a banner, a cloak, or a clock; as a maiden shot with arrows, often accompanied by female companions being martyred in assorted (often creative) ways. Feast October 21. She was also removed from the calendar in 1969.
In Christian art, the 3 terms nimbus, aureole and glory refer to the radiance around a sacred figure. Though used with overlap, a NIMBUS strictly refers to radiance around the head. It can take several forms, as seen in these holy cards, including a luminous disk (= halo). The nimbus first appeared in Christian art in the 5c., but the same device had been used in non-Christian art (eg Persian, Indian) for several centuries.
A GLORY is the combination of nimbus and aureole.
