English: Map of the Chao Phraya River in the Ayutthaya Kingdom (Thailand), 1726. Made by Francois Valentijn. The map is written in old Dutch. The English translation of the title is: 'The Great Siamese River Me-Nam, or Mother of Waters, its course and its tributaries displayed.' Centered on the Siamese capital of Ayutthaya and oriented to the west, the map extends inland several hundred miles from the Gulf of Thailand to central Thailand. Bangkok, identified as 'Fortres Banckok' appears on the left side of the map as no. 12. At the mouth of the Chao Phraya, described here as the Me-nam, a Dutch flag flies from building (no. 5) which is a VOC (Dutch East India Company) storehouse. This is one of the first published maps to offer accurate first-hand information on the interior of Siam. In total some 101 locations are referenced in the table below the map. The river is incorrectly called ‘Menam’ which is the Thai word for ‘river’. The correct name is the ‘Menam Chao Phraya’.
