The Month of Mary, According to the Spirit of St. Francis of Sales Thirty-One Considerations With Examples, Prayers, Etc.
by Gaspar Gilli, Saint de Sales Francis
About the author
Gaspar Gilli, often listed as Don or Father Caspar Gilli, is known for The Month of Mary, According to the Spirit of St. Francis of Sales. The work was translated and abridged from Italian by a Sister of the Institute of Charity, and an 1890 English edition helped preserve it for later readers.
The book is arranged as thirty-one meditations for May, presenting the virtues of the Virgin Mary through the gentle, practical spirituality associated with St. Francis de Sales. Modern catalog and ebook records consistently connect Gilli with this devotional classic, and it remains the main work by which he is remembered.
Reliable biographical details about his life beyond that book are scarce in the sources I could confirm. Because of that, the safest picture is of a Catholic priest-author whose lasting legacy is a small but enduring work of Marian devotion rather than a well-documented public career.
