In preparation for dissolving all monasteries in England, and seizing their assets, Henry VIII's Viceregent, Cromwell, sent out "visitors" "armed with articles of inquiry". "They were an ambitious, greedy, and unscrupulous set, chiefly concerned with securing the sort of information that would suit their purpose. The letters and reports or "comperts" which they sent to the Viceregent ..."
This makes me think the word is used as a fanciful basis for a grander act.

COMPERT (plural: comperta): Specifically, birth-tales in Old Irish literature that detail the conception and birth of a hero. Examples include the Compert Con Culainn (Birth of Cú Chulainn). Usually supernatural or extraordinary events involve themselves in the conception, such as the Druid Cathbad's seduction of Nessa after prophesying what the hour would be lucky for (begetting a king upon a queen!) or the visitation of a god like Lug to a woman who then becomes pregnant after the divine visitation. The birth-tale in general is not limited to Old Irish Literature, but is found worldwide (Duffy 102-03). Examples outside of Irish literature include the birth of Jesus, or the Buddha, or Leda and Hercules in Greek myth, Pryderi's conception in the First Branch of The Mabinogion, or King Arthur's conception in Arthurian legends.
