Astronomer at work. Historical artwork of a sighting tube or early telescope being used to observe stars through a window. Sighting tubes,which did not have lenses,were used for thousands of years before telescopes were developed. An assistant at left is consulting a book,possibly a star atlas. The stuffed crocodile hanging from the ceiling at upper left is a symbol,one often used in pharmacies to inspire awe in their patients. Early astronomy mostly involved astrology,and its practitioners often practised other sciences as well,such as alchemy,and herbal medicine,aimed at curing the ills of their patients,or making accurate prophecies | |
