The Triumph of St Thomas Aquinas is a painting by the Italian medieval artist Lippo Memmi, dating likely to 1323, when the former Dominican friar was canonized.

[1] The painting is a complex arrangement exalting the role of Thomas Aquinas as a scholar of religious knowledge, his placement among the Four Evangelists and philosophers.

In the center of the panel, the largest figure is the seated tonsured monk St Thomas Aquinas, below a Christ inside a mandorla.

A guide from 1867, while erroneously attributing the painting to Taddeo Gaddi, describes some of the contents including the quote from Proverbs 8:7, which Aquinas used to introduce his Summa contra gentiles[2][3] "Wherefore I prayed, and understanding was given me: I called upon God, and the Spirit of Wisdom came to me.

The guide provides a long elaboration of the lower figures, but careful examination fails to identify many of the attributes described.
