♄ is an astrological and astronomical symbol representing the planet Saturn.
This planet was named after Saturnus, the Roman god of agriculture, whose Greek counterpart was Cronus. In alchemical tradition, Saturn was associated with lead. The English word Saturday and Dutch zaterdag are derived from Latin Saturni dies, i.e. “day of Saturnus”.
But what about the symbol ♄? According to Wikipedia,
Saturn is usually depicted with a scythe or sickle, and the planetary symbol has apparently evolved from a picture of this attribute, in Kamateros (12th century) shown in a shape similar to the letter eta η, with the horizontal stroke added along with the “Christianization” of the other symbols <as we’ve already seen in the cases of Mercury and Venus> in the early 16th century.More photos of sea glass @ Shutterstock.
