The Perseus Digital Library has been hard at work on Minimum Viable Perseus (Perseus MVP). Designed as a static site and heavily inspired by the beloved but faltering P4 (and its awesome users), please check out our efforts here (sites.tufts.edu/perseusupdates) and try it out: beta.perseus.tufts.edu

I hope it's okay that I pulled this library in — it's much easier on the eyes than my off-the-cuff spectrum (live version: pletcher.github.io/ccc-2026-web...)

For an upcoming conference presentation: a heatmapped version of Greek tragedy to show how "epic" or "tragic" each line is (by averaging log likelihoods of lemmata appearing in each genre)—the Tutor's speech in S. Electra is particularly exciting to see in context pletcher.github.io/ccc-2026-web...

Work in progress: quantifying work/register distinctiveness of lemmata in Homer. One interesting result: "god" [θεός] and "human" [ἄνθρωπος] are much more likely to appear in speech than in narrative. HT www.dices.uni-rostock.de (for speech references) and github.com/francescomam... (for treebanks)
Chart showing log-likelihood (x-axis) and relative frequency (y-axis) of differentiating lemmata in the Iliad and the Odyssey. While most lemmata cluster towards the center—indicating low affinity for either epic—key words like "Odysseus" and "Hektor" are both frequent and have a strong affinity for the Odyssey or the Iliad (respectively). Other strongly Odyssean words include "suitor," "guest/stranger," "great hall," "home," and "swineherd"; strongly Iliadic, "Achilles," "horse," "war," "battle (verb)," and "battle (noun)." (Calculations were performed on Greek lemmata, but I translate them here for readability.)A chart showing the log-likelihood of speech versus narrative (x-axis) and relative frequency (y-axis) of lemmata in the Homeric epics. Words with strong narrative affinity (blue) include "proclaim," "speak," "go," "exchange," and "wingèd"; strong speech affinity, "evil," "guest/stranger," "know," "god," "human," and "home."

It’s weird that Helen of Troy being played by a black actress is a problem, but most of the rest of the Mediterranean, Greek and Turkish characters being played by incredibly fair and blond haired people of British, Irish and Scandinavian descent isn’t. And by weird, I mean entirely predictable.

I asked students to choose two Programming Historian (programminghistorian.org/en/lessons/) lessons beyond those assigned in class. So many lessons broken by Python and/or dependency updates—maybe we should prioritize platform stability? (I *love* PH; I do not love how frequently Python libs break)

Here we go again. Every so often tech makes an incursion into history, completely ignores that history is a rigorous discipline with a methodology, and then claims that a mystery or issue that historians have grappled with can be solved with an algorithm. www.bbc.co.uk/news/article...

Who “writes” an LLM-translated work of literature? Even if it isn’t a 1:1 copy, is an AI translation at scale just pure plagiarism? Any middle ground between stealing and creating new resources? (maybe relevant article: www.theguardian.com/books/2024/m... — Venuti probably relevant here too)

This is how news/media got around for most of human history. Sophocles' _Women of Trachis_ provides something of a thought experiment in what happens when the traditional avenue for news delivery becomes unreliable (hint: it ain't good)

From today's Chronicle of Higher Ed briefing. I am *never* an advocate of cutting programs. But I am curious to see if there will be the same type of "students aren't majoring in this, so let's cut the program" discourse around computer science as there always is for the arts and humanities.
But computer science is cratering. Four-year undergraduate enrollment in computer and information sciences plunged by 7.7 percent this fall — and it decreased almost twice as fast at the graduate level. The Clearinghouse data doesn’t say why, but it’s hard to ignore recent gluts of tech-company layoffs and questions about artificial intelligence taking coders’ jobs in a discipline that’s proven subject to ebbs and flows.

Here's another bit of conventional wisdom Zohran completely blew away: His speech was at well above a 10th-grade level. It was complex, erudite, punctuated by deep and fluent references. You don't have to condescend to voters with baby talk! Part of re-establishing norms is speaking like an adult.

Cleaned up the previous sentence embeddings comparisons—cleaner calculation of similarity for tragedies, and now both charts use the same scale (in autumn hues 🍂) It makes sense that tragedies overall are v. similar, but their similarities alone don't explain the lower-right messenger cluster

I might need to update the original plot, but so far it's interesting to note that the messenger similarities don't seem to be a result of consolidation across tragedies, which remain quite distinct (at least from the perspective of sentence embeddings) #dh #ancmedsky
Heatmap showing each Attic tragedy's similarity to the others. There is a distinct dark diagonal of perfect similarity -- self-comparison -- but not much other highlighting, suggesting surprisingly differentiated semantics (on average)

So sentence embeddings of messenger speeches in Attic tragedy show a modest but notable bump in semantic similarity toward the end of the 5th century (see attached image) — generic consolidation, maybe, but why? #ancmedsky #dh
