A match for the containers? 16th-17th century ivory vases

[JustAnotherTheory]

I think I'm able to narrow down the origin and denomination of these containers. In Theory and practice of design, and advanced text-book on decorative art (1894), available to view You are not allowed to view links. Register or Login to view., we can see the following chart:

   

These vessels are called hanaps, and on the right hand side of the diagram we can see a breakdown of the components of a hanap:

   

The features of the hanap's construction seem to match the vessels of the VMS. Here are a few examples:

   

Now in the book mentioned above, there is the following description for hanaps:

As luxury advanced, these drinking vessels became enriched in every possible way, and were ultimately regarded as articles for show rather than as articles for use — as rich adornments for rooms of state to be displayed on special occasions. The possession of such articles often indicated wealth ; and even the particular form of étage upon which they were placed indicated the rank of the owner. The enrichment of these hanaps appears to have been mainly effected by three modes of procedure, all of which bear upon the contour : first, by adding variety to the outline ; secondly, by developing parts ; and thirdly, by sub-division.

Does this perhaps indicate, that if indeed the vessels in the VMS are hanaps, then the Artist of the VMS was a member of a wealthy family?
