gold, cloisonné enamel, porphyry, gems, pearls, niello, wood core, Overall: 10.50 x 27.50 x 21.00 cm (4 1/8 x 10 13/16 x 8 1/4 inches). Gift of the John Huntington Art and Polytechnic Trust 1931.462

Commissioned by Countess Gertrude of Brunswick, this portable altar is one of the Guelph Treasure’s earliest and most sumptuous objects. The choice of white-speckled porphyry as the altar stone signals Gertrude’s worldly aspirations; an imperial color since classical antiquity, porphyry’s use was restricted to the imperial family. Historical figures of royal and imperial rank are depicted with Christ, the Virgin, apostles, and archangels along the altar’s sides, stressing the countess’s political ambitions and claim of imperial lineage for her own dynasty. The Latin inscription surrounding the altar stone reads, "Gertrude offers to Christ, to live joyfully in him, this stone that glistens with gems and gold."

translation of inscription: In order to live happily in Him, Gertrude presented to Christ this stone glistening with precious stones.
