Rubbish, not monuments, preserves daily life
Oxyrhynchus's thousands of discarded papyri (tax receipts, private letters, contracts, laundry lists, horoscopes) survived not because they were preserved but because they were thrown onto rubbish mounds in a climate dry enough to prevent decay. The result is a social record skewed toward the ephemeral and bureaucratic rather than the monumental, letting ordinary administrative friction, not grand events, carry the weight of history.
