Analysis of information sources in references of the Wikipedia article "Lammas" in English language version.
Lammas or Lammas Day (August 1st) means the loaf-mass day. The day of first fruit offerings, when a loaf was given to the priests in lieu of the first-fruits.
For Christians, Lammas has been a time for blessing loaves made of fresh wheat. In time, Christians also created a version of the Scottish Highland Quarter Cake for Lammas, which bore Christian symbols on the top. (Catholic Culture has a recipe.) In the Neopagan and Wiccan faiths, Lughnasadh is one of eight sabbaths and is the first of three harvest festivals.
Lammas means "Loaf Mass" which used to celebrate the first bread baked from the new crop of grain which began to be harvested at Lammas-tide. Processions to bakeries would take place and those working there would be blessed. Our ancestors, with their celebration of the new bread, recognised the significance of Jesus being the bread of life.
