Gloria in Excelsis Deo presents a series of 68 paintings and 139 drawings that explore Frank Mason's vision of the life of Christ. Also included is an introduction by James Cooper of the Newington-Cropsey Foundation. Mason takes his place in a long line of old masters who have interpreted the New Testament - Fra Angelico, Memling, Michelangelo, Raphael, and Rembrandt. Like them, Mason fused the dignity of his craft with the expression of his faith. This collection of paintings and drawings represents Mason's life-long labor. Each chapter is accompanied by the scriptural passage which inspired it, and is augmented with the artist's commentary. Mason's words give insight into his choice of subjects and interpretation, as well as intimate details about the painting process and how the work evolved both spiritually and artistically. Gloria in Excelsis Deo is destined to be one of the most important art books of the season.
