The Annals of Ecriu (abbr. AE) are an illuminated chronicle of Maltropian history compiled in the Monastery of Ecriu, Tyrmidra. Its entries span a period from 310 to 1410 AD. It is believed to have been written beginning about 750 AD, but the earliest surviving manuscript is a 15th century copy (Blaney MS 493) produced in Uisneach.
The Annals were compiled by a number of authors, mostly scribes from the monastery at Ecriu but also including annotations from the abbot and visiting monks. These writers use Irish and Latin interchangeably, a feature preserved in later transcriptions. The most prominent chronicler within the work is Julian the Scribe, sometimes erroneously given as its author. He was solely responsible for the entire period between 773 and 824 when he died.
The Annals of Ecriu are regarded as among the most factually accurate of the Maltropian annals, and are most important as a source for the Tumult, a period of civil war and famine which immediately preceded the rise of the monasteries as the great power centres of Maltropia. In particular, the entries by Julian the Scribe illustrate the changing conception of kings as figures of authority, although Ecriu remained more closely attached to its kings - the Uí Midire - than most. For example, Fiach Tána, who gained the throne after slaying his brother in battle, is described as a usurper who died after falling from his horse "on the Feast of Saint Joseph the good provider", proof that Nature itself rejected him as an unjust and therefore illegitimate monarch. However, current consensus is that he was attacked and murdered by ecclesiastics dissatisfied with his rule who then covered it up in their chronicle.
