Not that he was not a highly skilled artist or very intelligent.
It's just that, it is possible he is slightly overrated today as an inventor.
FROM LINK: y research revealed that Leonardo had owned a copy of di Giorgio’s treatise on civil and military machines. In the treatise, di Giorgio had illustrated and described a range of astonishing machines, many of which Leonardo subsequently reproduced in three-dimensional drawings. The illustrations were not limited to canals, locks and pumps; they included parachutes, submersibles tanks and machine guns as well as hundreds of other machines with civil and military applications.
This was quite a shock. It seemed Leonardo was more illustrator than inventor and that the greater genius may have resided in di Giorgio. Was di Giorgio the original inventor of these fantastic machines? Or did he, in turn, copy them from another?
I learned that di Giorgio had inherited notebooks and treatises from another Italian, Mario di Jacopo ditto Taccola (called Taccola “the jackdaw”). Taccola was a clerk of public works living in Siena. Having never seen the sea or fought a battle, he nevertheless managed to draw a wide variety of nautical machines – paddle wheeled boats, frogmen and machines for lifting wrecks together with a range of gunpowder weapons, even an advanced method of making gunpowder. It seems Taccola was responsible for nearly every technical illustration that di Giorgio and Leonardo had later improved upon.
So, once again, we confront our familiar puzzle: How did a clerk in a remote Italian hill town, a man who had never travelled abroad nor obtained a university education, come to produce technical illustrations of such amazing machines?
