Today in the calendars of both sides of the Roman Rite is the Feast of St. Catherine of Alexandria, virgin, martyr. As a matter of fact, she is celebrated by just about all Christians (who have any doctrine and history).
In the 2005 Martyrologium Romanum we find this entry:
Sanctae Catharinae, quam virginem fuisse Alexandrinam et martyrem nrratur, ingenii acumine et sapientia non minus quam animi robore refertam. Eius corpus in celebri coenobio monte Sina pia colitur veneratione.
It is said that angels bore her body to Mt. Sinai, where Moses received the Law.
In an interesting coincidence, it is also today the feast of St. Moses, a priest and martyr in Rome in 251. It is also the feast of Peter of Alexandria, a bishop and martyr in 311. I’m just sayin’.
Catherine of Alexandria is depicted usually with a palm, since she is a martyr, and a spiky but broken wheel, the instrument of her agony. She is also often depicted from medieval time onward as the subject of a “mystical marriage” with the Christ Child who is in the act of placing a ring on her finger. Another Catherine who is depicted this way is Catherine of Siena, recognizable in her Domincan habit. There are zillions of painting across several centuries of this popular theme for both saints. The painting I embedded, above, show both saints at the same time, which is rare.
Catherine of Alexandria is also one of the Fourteen Helpers, saints to whom people have over the centuries turn most often for intercession. Recourse to the Vierzehnheiligen was an especially popular tradition in German speaking lands.
Here is Catherine’s rather poetic Collect in the older, traditional Roman Rite:
Deus, qui dedísti legem Móysi in summitáte montis Sínai, et in eódem loco per sanctos Angelos tuos corpus beátæ Catharínæ Vírginis et Mártyris tuæ mirabíliter collocásti: præsta, quaesumus; ut, ejus méritis et intercessióne, ad montem, qui Christus est, perveníre valeámus:…
