It is, of course, a religious fetish. No doubt representing male fertility.
I can imagine a small army of museum restoration artists laboring over it to restore it to its original perfection. Then it will go on display, at the end of a large hall. The museum will charge people an hour's pay for the privilege of viewing it, and will sell replicas in the museum shop for two or three times that. The replicas will come with an explanatory booklet, explaining the sexualised religious practices of the ancients.
