This map is not so much a "block" as a "block" because it was carved on pottery and was made about four or five thousand years ago. Archaeologists speculate that people at that time first carved images on wet and soft mud blocks, then baked them in the sun and hardened them into pottery fragments.
This pottery painting depicts a city near Babylon, with mountains, valleys and settlements. Archaeologists have also found clay maps with different scales, which record streets, land property rights, town locations, and even cover the whole Babylonian region and paradise.
Compared with modern cartography and measurement standards, these pottery drawings are very simple, but they show that the society at that time had a centralized concept of city and land property rights, so it is necessary to record the relevant information of land property rights. In addition, scientists also found that these maps record numbers in decimal mode, which is different from the decimal system we currently use.

Two kinds of world maps are popular in the world. One is the world map of the Pacific pattern with the Atlantic meridian as the dividing line, which can also be called the "world map of the Pacific". It completely expresses the geographical relationship around the Pacific Ocean and divides the Atlantic Ocean on both sides of the map.
The other is the world map of the Atlantic pattern with the Pacific meridian as the dividing line, which can also be called the "Atlantic version of the world map". It completely expresses the geographical relationship of ring the atlantic and divides the Pacific Ocean on both sides of the map. The reason why these two versions of the world map have become worldwide versions is that they have followed two important principles when compiling the world map, namely, the principle of not cutting or cutting less land and the principle of dividing the map with the whole 15 latitude and longitude lines.
