Romulus and Remus, were the sons of Mars, the Roman god of war. An evil uncle threw them, as babies, into the Tiber river. They floated to land where a mother wolf fed and cared for them. Later, until adulthood, they were looked after by a shepherd. The tale of the twins being suckled by the wolf has been a symbol of the city of Rome. Rome was founded in 750 BC. The earliest written account of their story stems from the late 3rd century BC, 400 years later. Romulus, after having killed his brother, founded the city of Rome. He was the first king of Rome, founding many of its traditions and infrastructure. He ruled for many years.
Having told the story behind the calendar, now to the object itself. It is a writing instrument holder and a perpetual calendar. It has a depression for the holding of ink, a pen holder, adjustable, and a calendar that works in perpetuity. The image is of the she wolf suckling the twins. The detail is very good. It measures approximately eight inches long and four inches high. The bottom is covered in a green leather. I have cleaned it up a bit with some silver polish but could do with a bit more. I am not suggesting that it is silver but that's the polish that I used. I have not devalued it any way by cleaning it but it was covered in a thick layer of dust to match the decor of my house. It is from the 50/60s.
Thank you for looking.
