A mural from the lost Caral civilisation thought to be 3,800 years old has been revealed by archaeologists in northern Peru, Reuters reported.
The discovery was made at the Vichama archaeological site, which is located in Huaura province in modern-day Peru, about 150km (90 miles) north of the capital Lima.
Archaeologist Tatiana Abad said in a news conference in Lima that the mural represents the "announcement of the arrival of water," adding "it talks about the importance of water in times of crisis and the reflections that we can create from them."
A team of excavators brushed away the earth from the mural to reveal figures that depict a toad wrapping its hands around the head of a man.
Excavation started there in 2007. Experts believe the area used to be an ancient agricultural and fishing community.
The Secret City of Caral, in Peru's Barranca Province, is believed to be the oldest civilisation in the Americas, dating as far back as 3,000 BCE.
The civilisation is thought to have mysteriously declined in about 1,600 BCE due to climate change that may have played a role in its demise.
