This is an alabaster panel fragment, depicting the Trinity made in England in the second half of the 15th century. This fragment is the lower part of a tall panel. God the Father is enthroned in the centre with a cross bearing the figure of Christ between his knees. Christ with his head inclined to the left, is represented with long hair wearing a torse and loin cloth. There is a dowel hole just above the top of the cross which presumably held the Dove representing the third person of the Trinity.

There are two sorts of alabaster. Calcite alabaster is very hard and was used in ancient times. This object is made of gypsum alabaster which is a fine-grained, soft and smooth stone. Although at first glance it looks a little like marble, which it was intended to imitate, it was much easier to carve due to its softness, and alabaster objects were therefore significantly cheaper to produce. Marble does not originate in England, so it was imported if needed.

The carving of alabaster, mostly quarried in Tutbury and Chellaston near Nottingham, took on industrial proportions in England between the middle of the 14th and the early 16th centuries. The market for altarpieces and smaller devotional images was a large one. It included not only religious foundations but also the merchant classes. Many hundreds of English alabasters were exported, some as far afield as Iceland and Santiago de Compostela in north-west Spain.
