The piece is composed of detailed pencil strokes, creating a nuanced and expressive depiction. The composition features a central figure of God the Father, seated and holding a scepter, while God the Son is seated on his right, holding a dove symbolizing the Holy Spirit. The Holy Trinity is flanked by figures of Mary, John the Baptist, and the Archangels, showcasing the complex theological doctrine of the Trinity and its significance. This artwork is a compelling example of religious art, offering a glimpse into Wächter's artistic process and the importance of the Trinity in Christian belief.
