Observations of the triple quasar PG 1115+08 suggesting its nature as a single object diffracted by a gravitational lens are reported. The object was observed in a high-resolution image tube spectroscopic survey and with the MMT spectrograph on separate occasions. Comparison of the spectra of the three quasar components and their ratios reveals them to be identical within experimental accuracy, with variable contamination of the spectra of the weaker companions by the presumed actual quasar. CCD camera images of the system indicate the total magnitude of the two lens images to be 18.1, compared to a total system magnitude of 15.8, and the image geometry of PG 1115+08A,B,C is compared with that of the previously observed gravitational-lens double quasar 0957+56A,B.
