As to why da Vinci never delivered it, it has been speculated that he received a much more lucrative commission shortly thereafter and thus abandoned the painting at the time. Another hypothesis is that he perhaps made two versions of the painting, keeping one and delivering the other. Whatever the case, da Vinci continued working on the Mona Lisa (“Mona” more or less meaning “Madam”) up to around 1517.
