Yale
Azure, an open book proper inscribed in Hebrew characters “Urim v’Thummim.”

Adopted by the Trustees of Yale College in the early eighteenth century. The unknown designer of the seal identified the book as the Bible by words which read “Urim and Thummin,” probably names of sacred lots to be cast for the purpose of ascertaining the divine will (cf. Exodus 28:30); later mistranslated as “Lux et Veritas” for the college motto.

Timothy Dwight College in Yale University
Argent, a lion passant above a cross crosslet fitchy Gules; in a chief Gules a crescent Argent.

Probably invented by Jacob Hurd, a Boston silversmith, who engraved them on a tankard which he made in 1725 for Col. Timothy and Experience Dwight, grandparents of the elder of Yale’s two Timothy Dwights, who both served as president. Pierre la Rose made the first sketches for the arms at the suggestion of the Secretary of the University in 1934.
