Hesperus the coy construction consultant
Of course Hesperus was pissed off. He was a cripple and had been single for millenia, in anyone's book a long time to go without getting any. But it was a long time to plan as well, and our man H. was crafty. Through a complicated scheme he'd won Athena's hand in marriage. The release on his wedding night was the explosion that buried Pompeii. Coupling with the goddess of love brought pleasure hitherto unknown to this cosmos, but Hesperus had the goal and hope of a son. Alas Zeus forbade it. He was to be the only one to sire a new god.
Our man H. wouldn't stand for Zeus mucking with his lady. Neither could Hesperus match Zeus's ability to squirt a kid out his own femur. But H. had one thing going for him: his hands were as useful as his legs useless. When he wasn't in the bedchamber he was tinkering with toys for it, to Athena's immediate delight. And so they hatched a scheme.
Athena confided in Hera, the gossip of Olympus, that a son was more important to Hesperus than his pride. That evening he made a point to stay late in his workshop, toiling over the fires of Hades with anvil and iron. Athena lay alone. Zeus took the form of a cinnamon baklava and snaked into her room.
The next evening at dinner Zeus ordered course after course, boisterous and beaming. As the gods took their wine, Hesperus stood on his crutches and announced to one and all the happy news: they were with child. The feast continued for a full week in celebration and merriment, barring the occasional knowing glance among the ladies.
When Athena gave birth it was to a son. Our man H. had realized his dream. The night the young god was conceived, Hesperus had set his tools to work alone, while he and his wife canoodled beneath the workbench. A faux Athena lay in their bed that night, an engineering triumph and virtual match in every way. The mighty clanging and scraping did well to drown out the sounds of their long immortal love.
