author
A Catholic devotional writer remembered for a Marian work shaped by the spirituality of St. Francis de Sales, he is known today mainly through editions of The Month of Mary. His writing is simple, prayerful, and meant for daily reflection rather than abstract theology.

by Gaspar Gilli, Saint de Sales Francis
Very little biographical information about Gaspar Gilli is easy to confirm from reliable online sources, but he is credited as the author of The Month of Mary, According to the Spirit of St. Francis of Sales. That work appears in Project Gutenberg and other catalog listings, sometimes with the honorific "Don," suggesting a clerical or religious context.
The book is a devotional guide organized for the month of May, with daily meditations, examples, and prayers centered on the Virgin Mary and inspired by the teaching spirit of St. Francis de Sales. The style is practical and accessible, aimed at helping ordinary readers build a steady habit of prayer.
Because clear, well-sourced details about his life are scarce online, Gilli is best introduced through his surviving work: a compact piece of Catholic devotional writing that has continued to circulate in digital and reprinted editions.
