The Bellerophonic letters are believed to have originated in the 13th or 14th century BCE, and they were likely used by the Mycenaeans. However, the first written records of the letters do not appear until the 5th century BCE.
The Bellerophonic alphabet consists of 26 letters, each of which represents a different sound. The letters are written from left to right, and they can be combined to create words and sentences.
The Bellerophonic letters were used for a variety of purposes, including writing religious texts, poetry, and administrative records. However, they were eventually replaced by the Greek alphabet, which was more phonetic and easier to write.
Today, the Bellerophonic letters are still used by a small number of scholars and enthusiasts who study ancient languages and scripts. However, they are no longer used for everyday communication.
