Etymology
edit
The Greek letter Zeta with an abbreviation stroke, for Ζεύς ( Zeús ) , the Greek equivalent to the Roman god Jupiter .[1] The form changed from Classical and early Medieval ⟨Ƶ⟩ to one with a more salient cross, ⟨♃⟩ , in the 15th–16th century, at about the time that Christian crosses were added to ⟨☿ ⟩ , ⟨♀ ⟩ and ⟨♄ ⟩ , and so may have had a similar motivation.
Use of ♃ for Thursday, near the bottom of the calendar dial of this 13th-century clock tower.
♃
( astronomy , astrology ) Jupiter .
( alchemy , archaic ) tin .
( Can we verify (+ ) this sense?) ( botany , obsolete ) herbaceous perennial plant.
(the orbital period of Jupiter is 12 years) [2]
( rare ) Thursday .
Refers to the Latin phrase dies Iovis , which literally means "Jupiter 's day".
