English: Stained glass roundel memorial to Jeremiah Horrocks making the first observation and recording of a transit of Venus in 1639. The Latin reads "Ecce gratissimum spectaculum et tot votorum materiem": "oh, most grateful spectacle, the realization of so many ardent desires". It is taken from Horrocks's report of the transit (translation by G. Napier Clark, Sketch of the Life and Works of Rev. Jeremiah Horrox, Journal of the Royal Astronomical Society of Canada, Vol. 10, pp. 523–535, 1916)
