THE D TABLET
 

Let's now move on towards line Da5. The last glyph in line Da4 has the Sun located at η Hydrae:

Da4-8 (59) Da4-9 (64 - 4) Da4-10 Da4-11
July 23 (204) 24 (211 - 6) 25 26
AL TARF

RAS ALGETHI

 BRIGHT FIRE (*125.4) AVIOR (ε Carinae, *126.4) ο Ursae Majoris (*127.4)
Da4-12 (63) Da4-13 → 14 * 29½ Da4-14 Da4-15
July 27 (181 + 27) 28 29 (210) 30 (80 + 131)
*128 AL MINHAR AL SHUJĀ (σ Hydrae)

RAS ALHAGUE

 *130 η Hydrae (*131.0)

The Head of the Hydra is below the Cancer constellation and just above the equator (0º). And here began the Chinese 26th station Extended Net, stretching from July 30 (211) to August 25 (237 = 211 + 26). The hint has been given as Ox (a castrated Bull).

Here I once upon a time made a mistake by not documenting Da5-8 where it should have been. This is how it ought to be:

Da5-1 (67) Da5-2 Da5-3 Da5-4 Da5-5 Da5-6 Da5-7 Da5-8
Da5-9 (75) Da5-10 Da5-11 Da5-12 (78) Da5-13 Da5-14 Da5-15 Da5-16
 
Da5-17 Da5-18 Da5-19 Da5-20 Da5-21 (87)
