In 1646 she came, along with her brother, and greatly through his influence, strongly under the power of religion; and in 1652, after her father’s death, she renounced the world, and became one of the Sisters of Port Royal. She died amidst the persecution of the Sisters in 1661, a year before her brother.

There never certainly was a more singular story of youthful precocity than that which Madame Périer has given of her brother, accustomed as we have become to such stories in the lives of eminent men. Detecting the remarkable powers of the boy, his father had formed page 9very definite resolutions as to his education. His chief maxim, Madame Périer says, was always “to keep the boy above his work.” And for this reason he did not wish him to learn Latin till he was twelve years of age, when he might easily acquire it.

He endeavoured further to direct his son’s attention to the more marked phenomena of nature, and such explanations as he could give of them. But here the son’s perception
