Commissioned by a committee of Polish Americans formed to honor Kopernik on the 500th anniversary of his birth
The 16-foot circle symbolizes the earth’s orbit; fixed at the center is the sun, its rays extending to infinity
Mikolaj Kopernik (1473–1543), better known by the Latinized version of his name, Nicolaus Copernicus, laid the foundations of modern astronomy. In an age when philosophers and the Church believed that the entire universe centered on the earth, the Polish mathematician and churchman dared to suppose that the earth revolved around the sun.
The angular framework alludes to Kopernik’s homemade astronomical instruments, some of which were exhibited at the Franklin Institute before the sculpture’s unveiling
The memorial sculpture by Connecticut artist Dudley Talcott was commissioned and donated to the city by a committee of Polish Americans formed to honor Kopernik on the 500th anniversary of his birth. In Talcott’s design, the 16-foot circle symbolizes the earth’s orbit; fixed at the center is the sun, its rays extending to infinity.
The angular framework alludes to Kopernik’s homemade astronomical instruments, some of which were exhibited at the Franklin Institute before the sculpture’s unveiling. The 1973 dedication of Kopernik climaxed a year-long celebration of ethnic heritage by Philadelphia’s large community of Polish Americans.

A program of the Association for Public Art (formerly the Fairmount Park Art Association), Museum Without Walls: AUDIO is an innovative and accessible outdoor sculpture audio program for Philadelphia’s preeminent collection of public art.

A “multi-platform” interactive audio experience – available for free by cell phone, mobile app, or on our website – Museum Without Walls: AUDIO offers the unique histories that are not typically expressed on outdoor permanent signage.
Unlike audio tours that have a single authoritative guide or narrator, each speaker featured in Museum Without Walls: AUDIO is an “authentic voice” – someone who is connected to the sculpture by knowledge, experience, or affiliation.
Over 150 unique voices are featured, including artists, educators, scientists, writers, curators, civic leaders, and historians.
