Since 2008 CALiPSO started a systematic progressive visit to museums and institutions, thus beginning an International survey of Osiris and Ptah-Sokar-Osiris figures in exhibitions, storage-rooms and private collections.

Calipso is an independent, self-funded long-term project whose main purpose is to broaden the knowledge of such figures according to the following methodology:

• (Re)Tracing the figures in museums and private collections
• Carrying out a survey of the specimens
• Sharing gathered data and results with museums and scholars
• Production of an incremental on-line database

As the investigation advances, results and data will be made available through this website, others will be published in form of papers.

The name of the project is inspired by the Greek mythology and, more specifically, it refers to the nymph Calypso, the one who received and held on the Ogygian island the shipwrecked Odysseus for seven years. Calypso (Καλυψώ) derives from the greek καλύπτω (to hide, to conceal, to cover) and could mean "one who tries - or wants -  to hide." In fact, she lived in a deep and wide cave, that concealed gardens and sacred groves.
