CRIPTEX
A cryptex was a cylinder made up of rotating disks of letters. By arranging the letters in a certain order, the cryptex could be opened and a secret message could be retrieved from the center of the cylinder. If an attempt was made to crack the "cipher machine", the flask of vinegar contained inside would break and the acid would destroy the paper. The cryptex was recreated for the movie The Da Vinci Code from Leonardo Da Vinci's drawings.

ANCIENT REFRIGERATORS
Persian engineers by 400 B.C. had developed the technique of storing ice in the summer in the desert. In winter, the Persian people would bring ice from the nearby mountains and store it in vaults created in the middle of the desert.
These storages, called yakhchal, were some of the oldest refrigerators. They were also used to keep food cool and fresh during the hot summers.
At a glance, the structures look like large dome-shaped structures made of raw brick. Some of them were up to 18 meters high. Underneath the dome was a large underground space with warehouses. This space was connected to a wind trap, which helped to reduce the temperature to low levels during the summer

It included an instrument of passage for determining the time of night by the stars, a list of latitudes, a magnetic compass, a list of ports and harbors, a perpetual calendar, and a lunar index. The compendium could be used to determine the time, the height of the tide in ports, and calendar calculations.
What do you think of such complex mechanisms of the 16th century?

RANI-KI-WAV.
Rani-ki-Vav is a very complex structure, a multi-stage well, which is located in the city of Patan in India. It is 64 meters long, 20 meters wide and 24 meters deep. It is believed to have been built in the 11th century. However, archaeological work was almost never carried out here, because for many years the well was flooded by the Saraswati River and as a result all covered with silt.
Only at the end of the XX century began work on its clearing. Looking at what has been cleared, we can see that Rani-ki-Vav is not only a work of art, but also a testament to the incredible technologies of the past.

It was created in 100 BC. The dinosaur looks like an iguanodon. The innoscription is easily read in Russian "crocodilopardalik". Pardus or pardalik in ancient Russia called leopard.
Two proofs in one: the neighborhood of "extinct" reptiles with man and Russian writing before the Cyrillic alphabet.
