Hi Miranda,
I agree that we will never truly know the intent behind these pieces – whether they are meant to be abstract or not. I always like to consider how we make today’s sculptures, typically in class, and under the direction of an instructor. If I didn’t have these modern day means, my heart would probably look pretty abstract too. I think that the abstractness may stem from having to make things off of memory, and not having the large sum of tools we have today to create our pieces of art.
