|The University Seal|
|Evolution of Seals|
THE PRESENT SEAL OF THE UNIVERSITY OF SANTO Tomas (UST) is likened to a shield, quartered by the Dominican Cross on which is superimposed the sun of St. Thomas Aquinas, patron saint of Catholic schools, after whom the university is named.
On the upper left corner is the Papal Tiara, indicating the pontifical roots of the university. The upper right shows the lion, which is derived from the seal of Spain, indicative of royal patronage throughout the greater part of the university’s centuries-old existence. The lower left quadrant contains an image of a sea-lion, from the old seal of the City of Manila, the capital of the country, symbolizing that this university is a part of the Republic of the Philippines. The rose on the lower right corner is a symbol of the patronage of the Blessed Virgin Mary, under whose care the university was placed from its very beginnings.
The symbols are set in gold on a field of light blue, to honor the Marian color. The cross, however, is in blackand-white, the Dominican colors.
