A 'grant of arms' dating from 1554 was among the items acquired by the National Library of Ireland (NLI) in 2022.
The Stanyhurst Grant of Arms was purchased at auction earlier this year.
The 468-year-old Tudor manuscript is the earliest known Irish grant of arms in existence and described by the library as "remarkably well-preserved and visually impressive".
The arms were granted by Bartholomew Butler, Ulster King of Arms, to Nicholas Stanyhurst, Dublin city treasurer and alderman, and formerly Mayor of Dublin.
Other items acquired during the year included a photograph album owned by publisher and artist Elizabeth Yeats, sister of WB Yeats, which gives a glimpse into the life of the family, and vintage cinema posters from the 1960s.
Speaking about the new additions to the national collection during 2022, Acting Director of the NLI, Katherine McSharry said that additions to the library's collections help tell the stories of Ireland.
"The job of collecting Ireland’s memory in every age, whether from the 16th century or 2022, is a year-round one for the team at the NLI," Ms McSharry said.
"Tens of thousands of items – books, newspapers, photographs, letters, websites and much more – are added to the NLI’s collections and catalogued every year and all help us to tell the stories of Ireland."
