the Trinity and the Crucifixion, with Scenes from the Life of Christ 

This triptych, likely created in the mid to late 14th century, displays the artistic style of Luca di Tommé, a Sienese painter known for his adherence to the Sienese Gothic tradition. The central panel depicts the Holy Trinity with God the Father, the Holy Spirit, and Jesus Christ crucified. The scene is flanked by the Nativity on the left and Christ's Ascension on the right, each placed within an architectural frame. The gold ground of the work, a common feature in medieval painting, adds to the sense of divine presence and grandeur. The use of bright colors and detailed figures, especially the expressive faces, are characteristic of Luca di Tommé's work, highlighting his skill in rendering a range of emotions.
