I'm an Italian Noahide
The prohibition against worship of false gods is an integral part of the Noahide Laws .
Rambam says in Melachim uMilchamot 9: 2 (English translation by Rabbi E. Touger):
"We should not allow them (Gentiles) to erect a monument, to plant an Asherah, to make images and like even though they are only for the sake of beauty".
I have not understood whether from this ruling it is inferred, on the halachic level, that the Gentiles are forbidden to make sculptures and/or always tridimensional images of human figures even for non-cult purposes. Indeed, for the Jews it is undoubtedly always forbidden to make sculptures and tridimensional human images (Avodat Kochavim 3: 10-11), but is the ban also similarly extended for the Gentiles?
I give a practical example: in my hometown, Catania, in one of the main squares there is a large marble statue depicting the famous classical musician Vincenzo Bellini,my fellow citizen: is this a violation of the Noahide Laws?
