Well, I guess it's time for some serious literature.

Some impressions from medieval #Ladenburg: 1. City walls, gate and towers (12th/13th c.), 2. remains of the Carolingian church w. figural details wedged between the 12th-c. tower and later church (Sebastianskapelle). Unfortunately, I couldn't visit the 11th-c. crypt inside the church of St. Gall.

It's my favourite time of the semester again: Today I visited the University Library w. my Lampert of Hersfeld class to look at two original charters from the 11th c. issued by the archbishop of Mainz (1043) and the abbot of St. Maximin in Trier (c. 1047), respectively. Charterrific!

I was very happy to discover @jtpmedieval.bsky.social's review of my monograph in the new issue of @peritia.bsky.social. Especially since it contains my favourite comment on the book so far: '[...] Boniface gatecrashes Willibrord’s party too often and Summer wisely keeps him at arm’s length'.

It's always a personal highlight to visit the University Library at the end of the semester, but this time we were shown a real treat: Cod. Pal. lat. 864, containing excerpts from Gregory of Tours' Histories and Fredegar's Chronicles - written in Lorsch around 800! #MedievalSky

One for the early medieval/Merovingian nerds: Happy to receive a copy of Dáibhí's 2023 Jennifer O'Reilly Memorial Lecture, in which he argues that the name Rath Melsigi, the Irish monastery where Ecgberct (d. 719) settled after the plague of 664 according to Bede, derives from 'M[á]el-Sigi'... 1/3

The site of the 'Petite Marquise' in #Echternach, where structures dated to the 10/11th c. were discovered in 2020, is now covered with panels tracing the town's medieval history & showing some of the archaeological finds. Hopefully, we'll hear more about the preservation project 'Epternacum' soon.

During Pope Francis' visit to Luxembourg in 2024, Prime Minister Luc Frieden called Willibrord a 'European before the European Union'. In a brief article for @livunipress.bsky.social's blog, I reflect on the appl. of the label 'European' to early medieval missionaries. #MedievalSky
