The Diamond Sūtra of the second half of the sixth century on Mount Tai ranks among the most powerful monuments of China. On an area of some 2,000 square meters are engraved more than 2,500 characters of the sacred text; and on the boulders and rock escarpment bordering the sūtra, more than 60 colophons were added over the centuries, allowing us to trace the history of the site in great detail. Two of these colophons by the same calligrapher – a poem and an epigraph dated 1603 – are the subject of this paper.
