According to the literature, before the Goryeo dynasty, it used to be called Namcheon. Nammae, and Hwangmae. Later when Wangun arrived Bokhacheon to fight the troops of Hubaekje but was not able to cross the stream due to a flood, however, someone named Seomok helped, so Wangun was able to cross.
Later Wangun honored the victory from this area and quoted two letters of “I” and “Cheon” from “Iseopdaecheon”, and began to call “Icheon” to this day. (Dongguk Yeoji Seungram, Noojeong Edition) In addition, based on another story, when King Taejo Wangun was on his way to the southern region conquest, he asked for a fortune telling while he stationed and the fortune saying told him to name the area Icheon, so he granted the name Icheon. (Dongguk Yeoji Seungram Gojeok edition)
The meaning of the name was “It was advantageous since they were able to cross a big stream”. In the Book of Changes, Zhouyi “Iseopdaecheon” appears fourteen times and it mostly means that “when you build virtues, learning and physical strength, big streams that can be considered as tough times can be crossed and contribute with great honors, thus the whole world benefit”.
