"Megrez is from Al Maghrez, the Root of the Tail.

In China it was Kwan, and Tien Kuen, Heavenly Authority.

With the Hindus it may have been Atri, one of their Seven Rishis, and Vishnu-Dharma said that it ruled the other stars of the Bear."

If Megrez is the root of the tail it should be translated into 'marking the beginning of the end of Ursa Major'.

196 days beyond the northern spring equinox is the position of Alioth (the letter of which, ε, resembles viri):

Ga5-19 (130) Ga5-20 Ga5-21 (**104) Ga5-22 Ga5-23
Mimosa (193.9)   ψ Virginis (195.5), Alioth (195.8), Minelauva (196.1), Cor Caroli (196.3)   δ Muscae (197.5), Vindemiatrix (197.8)
October 1 (274) 2 3 4 13h = 197.8

It is also the position of the 'trident of Poseidon' (ψ Virginis), of Minelauva (the Barking Dog), and of Cor Caroli (the 'Heart' of King Charles).
