|Essential kit for ancient shepherds|
Perhaps the most intelligent herder cut notches on a stick for each day between mating and parturition then in the next year he could just tick off the days. This sounds the most plausible but I looked it up on the internet.
This is what I found:..... ancient shepherds would:
" Note the position of the bright star Deneb on the horizon at dawn on the day the sheep were mated. They could then expect the lambs when the star Vega occupied the same position at sunset."
I have checked this out on my Phillips "Planisphere" , Deneb is in the Western horizon in November and Vega is in the East in April, perhaps some astronomer out there can enlighten me. In the meantime I'll stay with notches on my stick.
