What types of skilled artisans were there in Babylon

The Babylonians inherited the technical achievements of the Sumerians in irrigation and agriculture. Maintaining the system of canals, dikes, weirs, and reservoirs constructed by their predecessors demanded considerable engineering knowledge and skill. Preparation of maps, surveys, and plans involved the use of leveling instruments and measuring rods. For mathematical and arithmetical purposes they used the Sumerian sexagesimal system of numbers, which featured a useful device of so-called place-value notation that resembles the present-day decimal system. Measures of length, area, capacity, and weight, standardized earlier by the Sumerians, remained in use. Farming was a complicated and methodical occupation requiring foresight, diligence, and skill. A recently translated document written in Sumerian but used as a textbook in the Babylonian schools is a veritable farmer’s almanac; it records a series of instructions and directions to guide farm activities from the watering of the fields to the winnowing of the harvested crops.
Babylonian artisans were skilled in metallurgy, in the processes of filling, bleaching, and dyeing, and in the preparation of paints, pigments, cosmetics, and perfumes. In the field of medicine, surgery was well known and often practiced, judging from the Hammurabi law code, which devotes several paragraphs to the surgeon. Pharmacology, too, doubtless had made considerable progress, although the only major direct evidence of this comes from a Sumerian tablet written several centuries before Hammurabi.
