BATH — Maine Maritime Museum will begin its New Worlds lecture series at 7 p.m. Tuesday, Sept. 29, with Don Treworgy, planetarium supervisor at Mystic Seaport in Connecticut, exploring “Consequences of Contact — The Sky At Sea: 500 Years of Navigation.”
In a slide-illustrated lecture, Treworgy will examine the contributions of Ptolemy, Copernicus, Kepler and others. The practical uses of astronomy in timekeeping, geography and navigation will be discussed, as well as historical instruments and their role in guiding early explorers such as Columbus.
Treworgy is a native of Milo and a descendant of a long line of seafarers. In addition to supervising the planetarium for the past 27 years and teaching celestial navigation for nearly 20 years, Treworgy is also in charge of monitoring hurricanes and other severe weather which might threaten the seaport.
The lecture begins at 7 p.m. in the Crooker Gallery of Maine Maritime Museum, and will conclude at 9 p.m. with refreshments. Dessert and gourmet coffee are included in the lecture price of $6.50 a person. Call Maine Maritime Museum for more information.
