... γ [Aquarii], 4.1, greenish, on the right arm at the inner edge of the Urn, and the westernmost star in the Y, is Sadachbia, from Al Sa'd al Ahbiyah, which has been interpreted the Lucky Star of Hidden Things or Hiding-places, because when it emerged from the sun's rays all hidden worms and reptiles, buried during the preceding cold, creep out of their holes!

But as this word Ah Biyah is merely the plural of Hibā', a Tent, a more reasonable explanation is that the star was so called from its rising in the spring twilight, when, after the winter's want and suffering, the nomads' tents were raised on the freshening pastures, and the pleasent weather set in. This idea renders Professor Whitney's 'Felicity of Tents' a happy translation of the original.

Allen continues:

"ζ, η, and π are included with γ under this designation by Ulug Beg - ζ in the center, marking the top of the tent; Kazwini, however, considered this central star as Al Sa'd, and the three surrounding ones his tents.

All these stars, with α [Sadalmelik], formed the 23d manzil, bearing the foregoing title.

γ, ζ, η, π, and τ were the Chinese Fun Mo, the Tomb.

It was near γ that the Capuchin friar of Cologne, Schyraelus de Rheita¹, in 1643, thought he had found five new satellites attendant upon Jupiter, which he named Stellae Urbani Octavi in compliment to the reigning pontiff; and a treatise, De novum Stellae circa Jovem, was written by Lobkowitz upon this wonderful discovery. 'The planet, however, soon deserted his companions, and the stars proved to be the little group in front of the Urn.'

¹ De Rheita is more deservedly famous as a supposed inventor, in 1650, of the planetarium, an honor also claimed for Archimedes of the 3d century before Christ, for Posidonius the Stoic, mentioned by Cicero in De Natura Deorum, and for Boëtius about the year A.D. 510.

This instrument is the orrery of modern days, named by Sir Richard Steele after Charles Boyle, Earl of Orrery, for whom one was made in 1715 by Rowley, from designs by the clockmaker George Graham.

Professor Roger Long constructed one eighteen feet in diameter, in 1758, for Pembroke Hall, Cambridge, where it probably still remains; and Doctor William Kitchiner mentioned one by Arnold, annually exhibited in London about the year 1825, that was 130 feet in circumference."
