Quiet field
242
The year was full. This aperture was quiet.
The surviving record for 242 is not blank. It does not, under the categories declared before this sweep, resemble a cluster of instruments, laws, or named firsts that would promote the year. Quiet is a description of the aperture, not of the century.
- Gordian III’s Persian war unfolding (campaigns 242–244)
