I scanned the pic from the Cristalleries Royales de Champagne (Bayel) brochure, and it really IS called Vénus. The other model called Bacchus has one hand above the head, the other points down.
There is no "Venus de Milo" in the Bayel collection (that is the one who got no arms due to an unfortunate accident with a washing machine) I can understand the confusion @ replacements, though.
I think the info on allaboutglass dot org may be incomplete.
