It analyses eight fascinating letters sent by Irish kings to the kings of England in the 13thC, while also providing a full transcription and translation of them in the appendix. Even better is that its open access: https://muse.jhu.edu/pub/423/article/997857/pdf31 Jul 2026 15:56 +0000at://did:plc:nrxti3sjbbas7hpr3iczexft/app.bsky.feed.post/3mrxcxez37c22https://bsky.app/profile/jmarshallmed.bsky.social/post/3moasqz2m5c2dVery enjoyable weekend in Cartmel at the Lake District Book Festival. Always a pleasure speaking alongside Sophie Ambler, discussing the foundation of Cartmel priory by William Marshal, the priory’s lands in Ireland, the Crusades, Magna Carta and everything in between! @historytcd.bsky.social14 Jun 2026 12:52 +0000at://did:plc:nrxti3sjbbas7hpr3iczexft/app.bsky.feed.post/3moasqz2m5c2dhttps://bsky.app/profile/jmarshallmed.bsky.social/post/3mmguwu6nz226This week I had the immense privilege of being part of a delegation from the Irish Manuscripts Commission as well as the Irish and British ambassadors to the Holy See to meet his holiness, Pope Leo XIV - a once in a lifetime experience. @historytcd.bsky.social22 May 2026 11:56 +0000at://did:plc:nrxti3sjbbas7hpr3iczexft/app.bsky.feed.post/3mmguwu6nz226https://bsky.app/profile/jmarshallmed.bsky.social/post/3mjs6y5ag3k22A change to looking at 13thC handwriting, but very nice to find my grandad Jack Crotty in the 1926 census when he was just 7 years old.18 Apr 2026 19:40 +0000at://did:plc:nrxti3sjbbas7hpr3iczexft/app.bsky.feed.post/3mjs6y5ag3k22https://bsky.app/profile/jmarshallmed.bsky.social/post/3mftynejccc27Very nice to be back in the old stomping ground today at the tail end of a brief but enjoyable and productive research trip @ihr.bsky.social27 Feb 2026 15:11 +0000at://did:plc:nrxti3sjbbas7hpr3iczexft/app.bsky.feed.post/3mftynejccc27https://bsky.app/profile/jmarshallmed.bsky.social/post/3mf7gepyv322mVery much looking forward to this tomorrow. I’ll be speaking about eight letters, and for a flavour, here is the salutatio of the earliest of these, sent by Cathal Crobderg Ó Conchobair to King John, which shows the practice of the Latin cursus alive and well in Gaelic Connacht.
