The paintings are located about 15 minutes walking distance from Machu Picchu. They depict a man and a cameloid in black.
The paintings are similar to others already known near the Inca citadel that also represent men, alpacas and other creatures, painted in ocher and black colors, Machu Picchu National Archaeological Park director Fernando Astete told EFE.
The two rock drawings may have been made in pre-Inca times, and they need more studies to confirm this theory.
The paintings are not recorded in Hiram Bingham's findings, Astete said, referring to the American archaeologist who discovered the Lost City of the Incas in 1911.
Machu Picchu was the birthplace of the Inca Empire or a fort where the last of the Inca warriors sought refuge during their struggle with Spanish conquistadors.
