Dermott's immediate impact was in replacing the regulations that Morgan had written with those of his own lodge in Dublin. In 1756 he published the Antient's own book of constitutions, entitled the "Ahiman Rezon", for which no meaning is known. Modeled on Spratt's Irish Constitutions, the regulations are comprehensive and well written, and are followed by an extended section devoted to songs. At the beginning, instead of Anderson's history, is an extended introduction attacking the original Grand Lodge, now calling itself the Grand Lodge of England, but saddled by Dermott with "the Moderns" in contrast to the "Ancient" usages of the new Grand Lodge. This name remains in use to the present day. His main weapon was satire. He started with an account of how he attempted to write a history which would better the others by describing masonry before Adam, but towards the end of the first volume, he fell asleep. He dreamed of a conversation with Ahimon, one of four sojourners from Jerusalem, about the futility of masonic histories, after which an ancient in a shining breastplate perused his first volume and pronounced, "Thou hast div'd deep into the water, and hast brought up a potsherd". He was woken by his neighbour's puppy eating his manuscript. Dermott then proceeded to a reasoned explanation of why a new Mason should not join a "Moderns" lodge, since their amended passwords would not be recognised by any of the other Grand Lodges which at that time existed. There follows a humorous account of their "unconstitutional fopperies", including Dermott's belief that their greatest masonic symbols were the knife and fork.
