"It is now possible to trace the medieval symbols for at least four of the five planets to forms that occur in some of the latest papyrus horoscopes ([ P.Oxy.（英语：） ] 4272, 4274, 4275 [...]). That for Jupiter is an obvious monogram derived from the initial letter of the Greek name. Saturn's has a similar derivation [...] but underwent simplification. The ideal form of Mars' symbol is uncertain, and perhaps not related to the later circle with an arrow through it. Mercury's is a stylized caduceus."

↑  Lilly, William. . 1659: 35, 37  [2022-01-30]. （原始内容存档于2022-04-09）. A chart with "℞" by a retrograde Jupiter appears on p. 35; on p. 37, describing the construction of the chart, Lilly says: "And because [Jupiter] is noted Retrograde I place the letter 'R', the better to informe my judgement."
