Tesserae V6 Now Available in Public Preview

A major new version of Tesserae, the free web tool for discovering textual parallels in classical literature, is now available at: tesserae.caset.buffalo.edu. Founded in 2008 by Neil Coffee (UB Classics) and James P. Koenig (UB Linguistics), the project helps scholars trace how ancient authors borrowed from, alluded to, and echoed one another This kind of close intertextual reading that is fundamental to understanding classical literature but painstaking to do by hand across large bodies of work.

A reader of Vergil, for instance, can search the Aeneid against the full works of Ovid or Lucan and reveal hundreds of verbal and thematic connections in seconds, ranked by the strength of the match. The tool searches a corpus of more than 2,100 Latin, Greek, and English literary works spanning Homer to the Medieval period.

Version 6 is a complete rebuild of the platform. It combines nine complementary methods of detecting parallels to find connections that earlier versions would have missed. These include AI-powered semantic matching and syntactic pattern recognition. Scholars across classics, digital humanities, and computational linguistics have used Tesserae in published research on authors from Homer and Vergil to Augustine and Prudentius, and the project's methods were even cited in the Federal Second Circuit's Authors Guild v. Google decision. Tesserae V6 was developed by Neil Coffee, building on foundational work by Chris Forstall and a continuing collaboration with Walter Scheirer (Notre Dame), with support from the NEH, the Swiss National Science Foundation, the UB Humanities Institute, and the UB College of Arts and Sciences. The tool is free and open source.
