The Casserole of Ozymandias

Pyrex lidded bowl containing 2 overlapping fragment sets carrying the text of Ozymandias, by Percy Bish Shelley scratched with steel into slate roof fragments. Fuller description later but to be installed in a limestone or similar cave as a method of long term storage of important texts. Overcomes problems like floating text fragments as found with 'The Dead Sea Scrolls'. Poem is a tribute to David Green; Google 'The Ozymandias Project'
