Simond was born at Riom, Auvergne, France on 12 October 1559. He was educated at the Jesuit College of Billom. After having been a novice at Verdun and then at Pont-Mousson, he entered into the order on 26 July 1576. After having taught rhetoric at Paris he resided for a long time in Rome as secretary to Claudio Acquaviva (1590–1608). In 1637 he was confessor to Louis XIII. He died on 7 October 1651 in Paris.

An essay in which he denied the identity of St Denis of Paris and St Denis the Areopagite (1641), caused a controversy. His Opera varia, where this essay is to be found, as well as a description in Latin verse of his voyage from Paris to Rome in 1590, have appeared in 5 vols (1696; new ed. Venice, 1728). To him is attributed Elogio di cardinale Baronio (1607).
