How to find the Horoscope

Finding the rising sign, and why it is harder than it looks.

Manilius, about 15 AD, in Thomas Creech's English verse of 1697. A 1-minute read · page 105 · free, every word

[p. 105] Perhaps these Precepts may appear too nice,For who can find the Horoscope in SkiesImmense, still circling with impetuous force,In Motion restless, and so swift in Course?Yet this not rightly fixt, our Art can boastNo certainty, and all our Labour's lost:As wretched Travellers are doom'd to stray,When those mistake, who should direct the Way.Because the Points which all the rest controul,Misplac'd at first, must influence the whole,And since the rouling Skies move swiftly on,A different Face is every moment shown,The Scheme must be uncertain, and the Birth unknown.

Yet tho' of greatest Vse, 'tis hard to gainThis Knowledge; and our Search is oft in vain:For who can in his narrow Breast compriseThe World immense, and who observe the Skies,Which with eternal Revolutions move,And Circling, measure the vast Orb above?What Diligence can e're describe its Face,What Art can fix in so immense a space?Those Points where East and West exactly fall,Which Crowns the Top, and which supports the Ball?
