It is possible the masks were a series representing the seasons; it was fairly common to personify the seasons and tie them to human stages of life; Spring being represented as a fair youth; summer as harvesters in field, autumn as wine makers or imbibers, and Winter as an elder. Another similar telleruhr is held by the Tiroler Landesmuseum in Austria. It is ascribed to Johann Franz Treibler who worked in Innsbruck around 1710/1720.The back of the dial bears practise engraving; 'JO', possibly an 'R' and a '20'. It is likely that the 'JO' refers to the maker, while 20 could be a personal serial number or the date 1720.
