There’s a story about Teresa of Avila, who is one of my favourite saints, as well as being since 1970 one of the two women, together with Catherine of Siena, who are officially “Doctors of the Church” (“Doctor” here means theologian, not medic.) Because she was engaged in setting up reformed Carmelite convents, she had to travel all over Spain and, because the Carmelites were an “enclosed order”, she had to travel in a covered wagon with no windows (which must have been pretty disagreeable in a Spanish summer).

One day, while so travelling with some of her sisters, the wagon tipped over while fording a river.
