The Bagan script, also known as the Burmese script, has its roots in the ancient Pyu script, which dates back to the 6th century CE. Over the centuries, the script evolved and was influenced by various languages, including Pali and Sanskrit. The Bagan script is an abugida, consisting of 33 consonant letters and 12 vowel symbols. This script was used to write the Burmese language, which is still spoken by millions of people in Myanmar today.
