IT Eppursimuove

Eppursimuove

Eppursimuove is located in the northwest of Italy. I deal with antique scientific instruments and their history. This passion has turned into a profession that leads me every day in search of ancient instruments that helped us to observe, measure, explore and know the sky and the earth. They still amaze and make us wonder, as they did for their original makers and users. For this reason they must be preserved and collected. Please feel free contact me if you need more information on listed items. Thanks.
