Moon in Aries

The Moon crosses a sign in about two and a quarter days, so a Moon in Aries covers only a short stretch of any month. Lilly 1659 clocks her full round of the twelve signs at a little over 27 days. A birth time helps here, because near a boundary the sign can change within the day.

Ptolemy (Ashmand's 1822 translation) treats the Moon's sign as a guide to the side of the mind that feels and reacts, and he sorts signs into tropical, bicorporeal and fixed for that purpose. Aries falls outside those three in that chapter, since elsewhere he calls it equinoctial and here he is silent on what equinoctial signs do. Lilly files Aries as moveable and cardinal alongside Cancer and Capricorn, which is how a later reader would fold it in.

Raphael's Guide of 1877, where the Moon's symbol is garbled in the scan and the entry is identified by its place in the list, gives a Moon in Aries a changeable, restless disposition and a liking for travel. Lilly's general note that the Moon is apt to shift her dwelling points the same way. Aries is a house of Mars, and Lilly's tables list no dignity for the Moon there.
