Thrasymachus Resources

I am on the hunt for suplementary resources for Thrasymachus. I have found these notes and this study guide helpful:
https://amissio.net/thrasymachus.html, https://web.archive.org/web/20041216085421/http://www.vroma.org:80/~abarker/thrascontents.html.

The above study notes are really helpful because they provide a translation and notes. Sadly, they only go up through chapter 7.

Are there other resources, study groups, or forum threads that might prove similarly useful, particularly for an autodidact?

Good question! Because a few days ago Luke Ranieri made available for free a picture book based on Thrasymachus:

I’ve made audios for the whole Thrasymachus book, here they are:

Increadibly helpful! Thank you!

Any suggestions on how to get the vroma site to display Greek fonts correctly? My attempts to download and install spionic were unsuccessful.

I am not a strong computer guy. It worked okay for me. You might also try Googling SPIonic and downloading it from a different source. This one might be a good option: https://www.inthebeginning.org/ntgreek/spionic.html. It has instructions for installation.
