 | | The Rosetta Stone is stone three in a series of three, a stone each for Ptolemy III, Ptolemy IV, and the Rosetta Stone, for Ptolemy V. Leap Year is implemented in Stone 1, the Stone of Canopus, for Ptolemy III. |
 | | Rosetta Stone is also used as a metaphor to refer to anything that is a critical key to a process of decryption, translation, or a difficult problem, e.g., "the Rosetta stone of immunology", "thalamo-cortical rhythms, the Rosetta stone of a subset of neurological disorders", "Arabidopsis, the Rosetta stone of flowering time (fossils)". |
