Origins and Design of the Columbia University Sundial

The Sundial was conceived as a commemorative gift from the Class of 1885 and was officially installed in 1910 during Columbia’s formative years at its new Morningside Heights campus. Designed by the esteemed McKim, Mead & White architectural firm and astronomy professor Harold Jacoby, the monument originally featured a massive, nearly seven-foot granite sphere known as the “Sunball.” This unique sphere, crafted from Vermont granite and weighing over 15 tons, was set atop a granite pedestal inscribed with the Latin phrase “HORAM EXPECTA VENIET” (“Await the hour; it will come”) (Columbia University Libraries; Columbia College Today).

The Sundial’s installation was part of a tradition where each graduating class would leave lasting gifts, such as monuments and gates, to connect the legacy of Columbia’s earlier campus at Madison Avenue to its new home (Columbia University Libraries).

Scientific Innovation and Functionality

Unlike typical sundials, the Columbia University Sundial was an advanced scientific instrument. Professor Harold Jacoby ensured it served not only as a timepiece but also as a calendar. At precisely noon, the Sunball cast a shadow across two bronze plates embedded in the pedestal, each inscribed with calibrations for the days and months. This allowed observers to determine both the date and the time with remarkable precision, accurate to within a fraction of a minute (Columbia University Libraries; Columbia College Today).

Physical Evolution and the Loss of the Sunball

By the 1930s, the Sunball began to develop structural cracks. Despite attempts to stabilize it with bronze rods and a steel band, safety concerns necessitated its removal in 1946. Since then, only the original granite pedestal and the bronze plates remain, and the Sundial no longer functions as a timekeeping device. While there have been discussions about restoring the Sunball, the monument’s current form has become iconic in its own right (Columbia University Libraries).

The original Sunball was rediscovered in Michigan in 2001, and while there have been ongoing efforts to return it, restoration remains pending (Columbia Senate Sundial Report).

With its central location on College Walk, the Sundial serves as a natural gathering point and meeting place—a role encapsulated in the phrase, “Meet me at the Sundial.” Over the years, it has evolved into Columbia’s “free speech corner,” becoming a vital stage for activism, rallies, performances, and student-led demonstrations. The Sundial played a significant role during pivotal moments in university history, including the 1968 protests and more recent demonstrations (Sundial Magazine; Columbia University Libraries).

The Sundial also hosts annual traditions, such as the Yule Log ceremony, and serves as the starting point for various campus events (Columbia Traditions).

The Sundial in Columbia’s Cultural Memory

The Sundial’s transformation from a scientific device to a symbol of civic engagement highlights its adaptability and enduring significance. It has inspired student publications like the “Sundial” magazine (Sundial Publication), and even appeared in student journalism by notable alumni such as Barack Obama. The monument stands as a silent witness to generations of student gatherings and intellectual discourse.
