In the monastery of Fossanova, near Terracina [Italy], St. Thomas Aquinas, Confessor and Doctor of the Church, of the Order of Preachers, illustrious for his noble family, holy life, and theological wisdom. Pope Leo XIII declared him the patron saint of all Catholic scholars. – Roman Martyrology for March 7
Much of Thomas Aquinas's writings were aimed at refuting Christian thinkers who had been led by their study of Arab philosophers to question the Eucharist and other church doctrines.1 Consequently in a number of images a turbaned figure lies vanquished below the saint, representing the errors of the Arab writers.
According to the Golden Legend Saints Peter and Paul themselves helped Aquinas understand the scriptures (image).
Aquinas was a Dominican, so portraits normally show him in the black and white habit of that order with a distinct tonsure. Often there is a shining sun on his breast, as in the second picture at right and this example. This may be a reference to two passages in the text of the Golden Legend used by William Caxton. In the first the friars in his convent saw a star shine "in manner of a sun" for three days before his death. In the second, some years later, a "brother Albert" was praying when Aquinas appeared to him in splendid garments: "on his breast he had a great stone which of his brightness cast out many rays of clearness and illumined all the church."
Some portraits show a dove at his ear to symbolize the inspiration of the Holy Spirit (example) and, less often, a monstrance referring to his work on the doctrine of Transubstantiation (example).
Aquinas was reported to have had several experiences of ecstasy in which he was lifted two or three feet from the floor. In one of these, while he was praying at the altar Christ said to him from the crucifix, "Thou hast written well of me. What reward wouldst thou have." He answered, "Lord, nothing but you."2 In another Christ said, again from the crucifix, "Thou hast written well of the sacrament of my body."3 In images of these visions he is often accompanied by angels rather than fellow Dominicans as specified in the texts example. I have not encountered any image that pictures him floating above the floor.
