Garum sorbet. Gaulish wine sorbet. A little Ithakan olive oil sorbet. Just a few of the Sorbets Virgilianae.

And in sermon mode: 'The eye of the Lord upon mee, makes midnight noone, and S. Lucies day S. Barnabies; It makes Capricorne Cancer, and the Winters the Summers Solstice . . . and turnes the jealousie of the sad soule into infallibility.' (Sermon on Ps. 32.8)
Since she enjoys her long night's festival,
Let me prepare towards her, and let me call
This hour her vigil, and her eve, since this
Both the year's, and the day's deep midnight is.

Agnes Blannbekin is famous for her foreskin vision, but her other visions are also pretty wild. She had a few of a giant talking lamb with human flesh(???) and a human face. Sometimes it also appeared to her very tiny sitting on the paten.
The book I’m cataloging now has everything: A beguine who has visions of eating Christ’s foreskin, anonymous confessor-scribes, lost (and found) manuscripts, censorship, battles over who gets to be head librarian, a guy named Pez, banned books being seized from the publisher…

This is such a good #HerBook read on the formidable Bathsua Makin. Showcasing her in a different light by the discovery of books attributed to her, it also touches on the female influence on children via book gifts, a subject I’ve been tipping away at via findings from our website!

I’ve been in Macbeth and seen it dozens of times, but the production I saw earlier this month was the first time it occurred to me how funny it is that Macbeth is sort of a bro-y idiot who defaults to violence, yet he constantly drops incredibly eloquent banger observations on his inner life.

In 2016, my partner worked for the department of Atmospheric Science at a major university. The morning after Trump’s election, people were crying in the hallways. I still can’t believe we elected him again and it’s still going on but even worse.
Exclusive: The Trump administration is moving to dismantle the National Center for Atmospheric Research in Colorado, according to a senior White House official, taking aim at one of the world's leading climate research labs.

Had the strange experience of cataloging a biography of Cato the Younger today that’s all about how he was the ideal senator. But to be honest it seems like he really sucked at it!

Love living in the city of my hero. I need a naked Ben Franklin Christmas ornament.
‘Every morning, he would strip naked, throw open the windows and pass half an hour reading or writing in the nude, before dossing down refreshed for another hour or so, sometimes answering the door in the buff to startled postmen.’

I just want to SEE one of the pamphlets printed by the Anabaptists at the Siege of Munster. Have wasted much time looking into this today for no practical reason. None are even digitized!

Such a beautiful polychrome terracotta group of two female figures sitting on a couch, leaning towards one another as if to share a secret. The older woman clasps her bare breast. They are thought to be Demeter and her daughter Persephone, but the identification is unsure. 🏺 1/ #ancientbluesky

I know it’s objectively not that bad, but being outside right now is so heinous. I want to just roll over onto the side of the road and give up on life. Is this seasonal depressing 🦋

Who built the seven gates of Thebes?
The books are filled with names of kings.
Was it the kings who hauled the craggy blocks of stone?
And Babylon, so many times destroyed.
Who built the city up each time?
Oh so it actually was the kings? Cool, question answered, thanks.
