The Leiden Convention, in 1931 standardized the critical symbols for papyrus, but the works of Grenfell and Hunt preceded it. Here are the main symbols used to show issues in Grenfell and Hunt's Oxyrhynchus papyrus deciphering:
- [ ] - Square Brackets
Indicate a lacuna.
- ( ) - Round Brackets
Resolution of a symbol or abbreviation.
- [[ ]] - Double Square Brackets
Indicate the letters between square brackets have been erased in the original document.
- < > - Angle Brackets
Letters omitted in the original.
- { } - Braces
Letters between braces were in the original but shouldn't have been.
- ...... - Dots inside brackets
The number of dots indicates the number of letters lost or erased. Best guess.
- ...... - Dots outside brackets
Indicate illegible letters.
- Dots under letters
Indicate letters about which the papyrologist is uncertain.
- Generally, only the first time an abbreviation or symbol is used it will be explained.
- Words are separated in the transliteration even though they are run together in the original.
- Use of Numerals:
- Small Roman Numerals - refer to the number of the papyrus
- Large Roman Numerals- refer to the number of the column
- Arabic Numerals - refer to the number of the line.
