The cycle of Venus is 584 days long. If Gb1-21 should represent Venus, then number 314 can be used to divide its cycle:

314 is counted from honu at Gb6-26 (with Gb8-30 counted twice)
314		269
	Gb1-21 (315)
	270
584

During 263 days in a row the morning star is visible, and so behaves also the evening star aspect of Venus. Between the evening and morning stars there are 8 days (when Venus is invisible). 263 + 8 = 271.

This idea should be elaborated, and it will be done in the following detour.
