+## Investigation Details
Uncial Antiqua was designed by Brian J. Bonislawsky under the studio name Astigmatic (AOETI). It combines Uncial and Half Uncial letterforms.
2. **Repository name search**: Searches for "uncial antiqua", "uncialantiqua", and "astigmatic font" returned no canonical font source repositories on GitHub.
3. **Astigmatic website**: astigmatic.com was not investigated further as Astigmatic is a commercial foundry that releases fonts for free distribution but typically does not publish editable source files.
-### Status
-
-No canonical upstream repository with UFO or Glyphs sources was found. No source block was added to `METADATA.pb`.
-
-### Conclusion
-
Uncial Antiqua was contributed to Google Fonts by Astigmatic, a commercial type foundry. While the font is released under OFL, the source files have not been made publicly available. This is consistent with Astigmatic's other Google Fonts contributions.
