also: Trinity with souls
The Bosom of Abraham Trinity is a rare iconographic subject found apparently only in English medieval alabaster sculpture, with just twelve surviving examples - five free-standing statues, including those in the Burrell Collection in Glasgow and the Museum of Fine Arts, Boston, and seven high-relief panels of the usual altarpiece size. The composition adapts the 'Throne of Mercy' Trinity: God the Father, with the crucified Christ, holds or supports a cloth or napkin containing tiny figures of the saved souls, a motif borrowed from earlier images of Abraham sheltering souls in his cloak on 13th-century French cathedral facades. The Boston figure, dated 1420-50, shows nine souls including a crowned king and a bishop, with donor figures kneeling at God's feet. Both the subject and its modern name were defined by art historians; the type was first published by W. L. Hildburgh in 1933.
