A rare Omer calendar, brass on wooden base.The Netherlands, circa 1800The 49 days of Omer are beautifully inscribed on the turning dial. Very delicate and uncommon object.H_25 cm L_20 cm (9 ²⁷/₃₂ x 7 ⁷/₈ in)The period of the « Omer » begins the second night of Passover and continues until Shavouot. Literally translated, Omer means a sheaf. It refers to the measure of grain that was once offered at the holy temple in Jerusalem. The Torah commanded that seven weeks be counted for the Omer. Every evening of the 49 days of Omer, the specific day is cited. It also symbolizes the spiritual elevation – like the climbing of 49 stairs – needed to reach the fiftieth day (the day after the Omer), which is when Jews celebrate, on the day of Shavouot, the receiving of the Torah on Mount Sinai.
