The houses of Muttatus are known as illams and mattams, the former being the name of all Nambutiri houses. They are generally built beside some well-known shrine, with which the inmates are professionally connected. The dress of both men and women resembles that of the Nambutiri Brahmans, the injunction to cover the whole of the body when they go out of doors being applicable also to the Manayammamar. Girls before marriage wear a ring and kuzal on the neck, and, on festive occasions, a palakka ring. The chuttu in the ears, and pozhutu tali on the neck are worn only after marriage, the latter being the symbol which distinguishes married women from widows and maidens. Widows are prohibited from wearing any ornament except the chuttu. In food and drink the Muttatus are quite like the Nambutiris. The Muttatus are the custodians of the images, which they take in procession, and wash the stone steps leading to the inner sanctuary. They live by the naivedya or cooked food offering which they receive from the temple, and various other emoluments. It may be noted that one of the causes of their degradation was the partaking of this food, which Brahmans took care not to do. The Muttatus are generally well-read in Sanskrit, and study astrology, medicine, and sorcery. The social government of the Muttatus rests wholly with the Nambutiris, who enforce the smartavicharam or enquiry into a suspected case of adultery, as in the case of a Nambutiri woman. When Nambutiri priests are not available, Muttatus, if learned in the Vedas, may be employed, but punyaham, or purification after pollution, can only be done by a Nambutiri. Like the Nambutiris, the Muttatus strictly observe the rule that only the eldest male member in a family can marry. The rest form casual connections with women of most of the Ambalavasi classes. They are, like the Brahmans, divided into exogamous septs or gotras. A girl is married before or after puberty. Polygamy is not uncommon, though the number of wives is never more than four. Widows do not remarry. In their marriage ceremonies, the Muttatus resemble the Nambutiris, with some minor points of difference. They follow two sutras, those of Asvalayana and Baudhayana, the former being members of the Rig Veda and the latter of the Yajur Veda. The former omit a number of details, such as the panchamehani and dasamehani, which are observed by the latter. According to a territorial distinction, Mussad girls of North Malabar cannot become the daughters-in-law of South Malabar families, but girls of South Malabar can become the daughters-in-law of North Malabar families.
