from Banten, Bogor, Priangan, and Cirebon. In Central Java, Sundanese is spoken in some of the Cilacap region and some of the Brebes region. It is known that the most refined Sundanese dialect — which is considered as its original form – are those spoken in Ciamis, Tasikmalaya, Garut, Bandung, Sumedang, Sukabumi, and especially Cianjur (The dialect spoken by people living in Cianjur is considered as the most refined Sundanese). The dialect spoken on the north coast, Banten and Cirebon are considered less refined, and the language spoken by Baduy people is considered the archaic type of Sundanese language, before the adoption of the concept of language stratification to denote rank and respect as demonstrated (and influenced) by Javanese. Today, the Sundanese language is primarily written in Latin script. However, there is an effort to revive the Sundanese script, which was used between the 14th and 18th centuries. For example, street names in Bandung and several cities in West Java are now written in both Latin and Sundanese scripts. Religion The initial religious systems of the Sundanese were animism and dynamism with reverence to ancestral (karuhun) and natural spirits identified as hyang, yet bears some traits of pantheism. The best indications are found in the oldest epic poems (wawacan) and among the remote Baduy tribe. This religion is called Sunda Wiwitan ("early Sundanese"). The rice agriculture had shaped the culture, beliefs and ritual system of traditional Sundanese people, among other the reverence to Nyai Pohaci Sanghyang Asri as the goddess of rice and fertility. The land of Sundanese people in western Java is among the earliest places in the Indonesian archipelago that were exposed to Indian Hindu-Buddhist influences. Tarumanagara followed by Sunda Kingdom adopted Hinduism as early as the 4th century. The Batujaya stupa complex in Karawang shows Buddhist influences in West Java, while Cangkuang Shivaic temple near Garut shows Hindu influence. The 16th-century sacred text Sanghyang siksakanda ng karesian contains the religious and moral rules, guidance, prescriptions and lessons for ancient Sundanese people. Around the 15th to 16th centuries, Islam began to spread among the Sundanese people by Indian Muslim traders, and its adoption accelerated after the fall of the Hindu-animist Sunda Kingdom and the establishment of the Islamic Sultanates of Banten and Cirebon in coastal West Java. Numerous ulama (locally known as "kyai") penetrated villages in the mountainous regions of Parahyangan and established mosques and schools (pesantren) and
