objects in the museum's collection. The museum defines the late period as extend from 1150 to 1550, but allows for a lot of cross-over with the earlier golden age of Irish art (including some of the later croziers, bell-shrines and cumdachs). According to Kelly, the museum displays its collection of later work under three groupings: "bellatores (those who fight), oratores (those who pray) and laboratores (those who work)". Governance The museum's stated function is to hold the nation's "archaeological, ethnographical, classical and Egyptian collections. The Division is also responsible for the administration of various statutory functions such as the acquisition of archaeological objects claimed as the property of the State and the regulation of licences to export and alter archaeological objects". Its day-to-day work is preoccupied with recording and cataloging newly found artefacts, which in 2019 mostly involved bog finds, lithics and ceramics.
