low tide. Culture Cosmogony and religion According to early Chamorro legend, the world was created by a twin brother and sister, Puntan and Fu'uña. As he lay dying, Puntan instructed his sister Fu'uña to make his body into the ingredients of the universe. She used his eyes to create the Sun and Moon, his eyebrows to make rainbows, and most of the rest of his parts into various features of the Earth. Once her work was complete, she descended on an island called "Guåhan", and transformed herself into a giant rock. This rock split, and from it emerged all human beings. Some believe that this rock was once located at the site of a church in Agat, while others believe it is the phallic-shaped Laso de Fua located in Fouha Bay in Umatac. Ancient Chamorros engaged in ancestor veneration, but did not practice a formal "religion" in the sense of worshiping deities. At least one account by Christoph Carl Fernberger in 1623 holds that human sacrifice was practiced to placate a "great fish". This claim may be related to a Chamorro legend about why the island of Guam is narrow in the middle. According to the legend, a gigantic fish was gradually eating away at the island from both sides. Although the ancient Chamorros supposedly had magical abilities, the huge creature eluded them. When the men were unsuccessful in hunting it down, the women used their hair to weave a net, which grew larger as they sang. The singing enchanted the fish, and lured it into the giant net. Castes and classes Chamorro society was divided into two main castes, and continued to be so for well over a century after the Spanish first arrived. According to historical records provided by Europeans such as Father Charles Le Gobien, apparent racial differences existed between the subservient Manachang caste, and the higher , the Manachang being described as shorter, darker-skinned, and physically less hardy than the Chamori. The Chamori caste was further subdivided into the upper-middle class Achoti/Acha'ot and the highest, the ruling Matua/Matao class. Achoti could gain status as Matua, and Matua could be reduced to Achoti, but Manachang were born and died as such and had no recourse to improve their station. Members of the Manachang and the Chamori were not permitted to intermingle. All three classes performed physical labor, but had specifically different duties. Le Gobien theorized that Chamorro
