The Apparitions of the Moon. Phases Lunæ.
[Illustration]
The _Moon_ shineth not by her own _Light_ but that which is borrowed of the _Sun_. _Luna_, lucet non sua propria _Luce_, sed mutuatâ a _Sole_.
For the one half of it is always enlightned, the other remaineth darkish. Nam altera ejus medietas semper illuminatur, altera manet caliginosa.
Hereupon we see it in _Conjunction_ with the _Sun_, 1. to be obscure, almost none at all; Hinc videmus, in _Conjunctione Solis_, 1. obscuram, imo nullam: in _Opposition_, 5. whole and clear, (and we call it the _Full Moon_;) in _Oppositione_, 5. totam & lucidam, (& vocamus _Plenilunium_;) sometimes in the half, (and we call it the _Prime_, 3. and _last Quarter_, 7.) alias dimidiam, (& dicimus _Primam_, 3. & _ultimam Quadram_, 7.)
Otherwise it waxeth, 2....4. or waneth, 6....8. and is said to be _horned_, or more than half _round_. Cæteroqui crescit, 2....4. aut decrescit, 6....8. & vocatur _falcata_, vel _gibbosa_.
