Lomer, also known as Laumer, Laudomarus, Launomar, or Launomaro, is a Christian saint whose feast day is January 19. He founded an abbey at Corbion near Chartres in present-day France. The vita of Saint Lomer reveals that, as a youth, Lomer was a shepard, before being accepted into the monastery of St. Mesmin, near Orleans, and would eventually become a priest in Chartres. The vita also states that Lomer lived to be more than one hundred years old. One known copy of this vita was begun by Orderic Vitalis while he was copyist at the library of Saint-Évroul.
