True, yet with a but:

• There are not many other facts supporting the idea that the Greeks in fact used this kind of tool for their daily work.
• There are also evidence that the wheelbarrow might have been used also in China.
• There is no real unitary terminology for this vehicle, meaning that e.g. in the 19th century wheelbarrows in Europe were made of wood, while in England in 1822 they were made of iron.
