Hello Wanax, 

 concerning Inana, when removing my edit you said you just read the ETCSL translation of the myth and couldn't find any of this stuff there.  

 Did you read lines 29 to 45 ? Did you read this: 

 Lines 29-32: Having drunk cleansing water from the Ulaya river, Inana stamped on the scorpion and cut off its tail. Like a lion it bellowed in an angry roar but its cries died down. …… she threw it …… and made it secure. 

 Lines 33-38. Having heard its …… cries, …… poured forth the ……, the clay of creation, …… and laid it ……. 
 2 lines missing …… the great lady of heaven delivered those words to An. 

 Lines 39-45: Having heard those words, An slapped his thighs in ……, his voice filled with sighs of grief: "What has my child done? She has become greater than me! What has Inana done? She has become greater than me! From now on, the normal length of daylight becomes shorter, and daylight converts to night-time. From today, when the day's watch is three units long, daylight is equal to night-time." 

 The Fall equinox is described beautifully as  " 
 From now on, the normal length of daylight becomes shorter, and daylight converts to night-time. From today, when the day's watch is three units long, daylight is equal to night-time." 

 I have made that discovery in 2013, and it has been recognized by the CAENO Foundation (CAENO.org). I am hereby soliciting your critical review, along with a chance to let me answer to any objections you may have regarding what I consider being a major discovery, not possible even a couple of years ago. Call me ! ;-) 

 Sincerely,
