Thuria, mad queen of heaven!

"Cluros, the farther moon, was just

rising above the horizon to commence his leisurely journey

through the heavens. Eight zodes later he would set--a trifle

over nineteen and a half Earth hours--and during that time

Thuria, his vivacious mate, would have circled the planet twice

and be more than half way around on her third trip. She had but

just set. It would be more than three and a half hours before she

shot above the opposite horizon to hurtle, swift and low, across

the face of the dying planet.

 

It was the age-old miracle of the

Martian nights that is always new, even to Martians--two moons

resplendent in the heavens, where one had been but now;

conflicting, fast-changing shadows that altered the very hills

themselves; far Cluros, stately, majestic, almost stationary,

shedding his steady light upon the world below; Thuria, a great

and glorious orb, swinging swift across the vaulted dome of the

blue-black night,"

 

The Chessmen Of Mars      Edgar Rice Burroughs

 

 

any of the few who saw the  dire "john Carter" will reember if anything of the  loosely based plot that  the two martian moons  in that movie  were lunar spheroids in close o double rbis showing identical phases  not the fast moving low horizon thuria    orbiting three times a night "nocturnal Martian scene one of splendid and weird

grandeur." as Princess of Mars   desscribes it

based as theey were on Deimos and Phobos  orbits  (albeit ERB moons   were  more Swiftan than  Hall) the main  plot  device in the Barsoom books was the difficulty of  anyone  to  hide  under Thurias rapid  binary bright light
