|The Trinity, 1425, Masaccio|
Below that are the figures of Joseph and Mary, painted life-size with Mary interceding for humanity. Slightly below and flanking it on either side, just outside the niche, are portraits of the donors of the work, the Leni family, Lorenzo and his wife. Below that is the open tomb with a skeleton above which are inscribed in Latin the haunting words, "I was that which you are. You will be that which I am." Though the painting is somewhat deteriorated today, badly in need of cleaning, the figures are in every way realistic and believable, a vision, as it were, of mankind's relationship to God the Father, the Son, and the Holy Ghost--a presentation so perfect and powerful as to impact the viewer both emotionally and spiritually. Its impact on artists especially left them with a whole new way of seeing and painting both man and God.
