Over the course of the 12th & 13th centuries in Europe, the layout of the page in books became increasingly complex, due to changes to reading practice with the rise of scholasticism & the university. The sophisticated architecture of the page compresses an amazing amount of info into this space.
A powerpoint slide showing a page from a late 12th century copy of Peter of Lombard's commentary on the Psalms an epistles. To the left in large script is the scriptural text. To the right, in smaller script, is the commentary. I have outlines in various colors the different components that coordinate each but of commentary with the word or verse they gloss and that coordinate them with the auctor responsible for the commentary.

The Cave Research Unit of Hebrew University of Jerusalem discovered a partial skull during a survey of Manot Cave in 2008. Dated to 60,000 to 49,000 years ago, Manot 1 lived at a time when a modern founder population began to disperse throughout the world.
Illustration of Manot 1 partial skull. Text: The Cave Research Unit of Hebrew University of Jerusalem discovered this partial skull during a survey of Manot Cave in 2008. The cave had previously been hidden when an entrance was opened by a bulldozer, and the calvaria lay on a flowstone shelf in a side chamber of the main gallery. A crust of calcite on the calvaria allows a minimum age estimate from the decay of uranium into thorium, this suggests the individual lived at least 60,000 to 49,000 years ago. The overall anatomy of the skull resembles modern humans but it has some shape similarities with Neandertals, including the flattened area flanking the lambdoidal suture and a shallow suprainiac fossa. Israel Hershkovitz and collaborators have suggested that the individual belonged to a population that made early Upper Paleolithic artifacts and had some mixture from Neandertal populations.

Rapid natural selection across the last 5000 years, a complex speciation to kick off the hominin lineage, and a single pulse of Neandertal ancestry into recent people around 47,000 years ago. Those are some of the big stories coming from DNA this year.

Saw some really lovely penwork decoration today. Dutch flourishing from 15th century has distinct regional features, this style is from Haarlem. More importantly, the happiness just jumps off the page!

The Hague, KB, 1900 A 406

Sometimes, because parchment undulates, even in digital facsimile we can see medieval illuminations as they would have looked with an indirect light source. Light and shadow made the page come alive every time it was used, for example, in a liturgical context.

A richly decorated manuscript page with many applications in gold that are well visible because of the uneven surface of the parchment. Light reflects from these letter.

Nifty 1501 edition of the letters of Pliny the Younger. But for me, the star of the show is the printed book’s manuscript binding: a recycled leaf from a ca. 11th/12th-century copy of Gregory the Great’s Moralia in Job. Lovely hierarchy of script! #fragmentology #ManuscriptFragment #BindingFragment

Scalp mass, 33M. Just a nice example of soft tissue Rosai-Dorfman disease. I think this low power “pale->pink->blue” look is a good low power clue. In addition to S100 protein, Karen Rech’s group here at Mayo have shown OCT2 to be valuable in this dx. pubmed.ncbi.nlm.nih.gov/33177341/
