Apparently busy with other concerns, the College’s Trustees adopted the seal of the former Williamstown Free School upon incorporation of Williams College in 1793. The Free School seal pictured three students with books in their hands standing before their instructor who was seated in a chair. Encircling the device was the legend: E Liberalitate E. Williams Armigeri, “Through the generosity of E. Williams, Esquire.” In 1802, the Trustees voted to procure a new seal, but this seal, our current one, did not come into common usage until 1805.
Over the years, the new seal has been printed with many variations. Retaining the original legend, it currently pictures a globe, a telescope, an inkstand and pen, a scroll, a spray of laurel, and a miscellaneous object, perhaps a book, all beneath the rays of the sun. The objects in the seal are said to represent the four sciences of the Quadrivium: Geometry, Astronomy, Arithmetic and Music. Laurel is generally regarded as a symbol of honor, victory and of excellence. The rays of the sun are perhaps an allegorical reference to learning.
Kwa sababu ya shughuli nyingi, Wadhamini wa Chuo walichukua muhuri wa zamani wa Shule ya Bure ya Williamstown wakati wa kuingizwa kwa Chuo cha Williams mnamo 1793. Muhuri wa Shule ya Bure ulionyesha wanafunzi watatu wakiwa na vitabu mikononi mwao wakiwa wamesimama mbele ya mwalimu wao aliyekuwa ameketi kwenye kiti. "Kutokana na ukarimu wa E. Williams, Esquire, ""E Liberalità E. Williams Armigeri"" ilitengenezwa na kuundwa kwa muhuri mpya wa E. Williams, ambayo ilitengenezwa mwaka 1802. Kwa miaka mingi, muhuri huo mpya umechapishwa kwa njia mbalimbali. Kwa kuhifadhi hadithi ya awali, sasa inaonyesha dunia, darubini, inkstand na kalamu, kitabu, dawa ya laurel, na kitu kingine, labda kitabu, vyote chini ya miale ya jua. Vitu vilivyo katika muhuri huo vinasemekana kuwakilisha sayansi nne za Quadrivium: Jiometri, Astronomia, Hesabu na Muziki. Kwa kawaida laurel huonwa kuwa ishara ya heshima, ushindi, na ubora. Huenda miale ya jua ikawa ni mfano wa kujifunza.
