Astronomical symbols

This excerpt from the 1833 Nautical Almanac demonstrates the use of astronomical symbols, including symbols for the phases of the moon, the planets, and zodiacal constellations.
“Designation of celestial bodies” in a German almanac printed 1850[1]

Astronomical symbols are symbols used to represent astronomical objects, theoretical constructs and observational events in astronomy. The earliest forms of these symbols appear in Greek papyri of late antiquity. The Byzantine codices in which the Greek papyri were preserved continued and extended the inventory of astronomical symbols. New symbols were further invented to represent many just-discovered planets and minor planets discovered in the 18th-20th centuries.
