She is known as the 'Moon Goddess' and may be related to the Egyptian
lion-headed sun goddess 'Tefnut' of Heliopolis who represented the
moisture in the air, clouds, mist, dew, rain and later possibly
the rivers of Britain (and nowadays, probably the weather in Manchester
!). She was the partner of 'Shu', God of the air, son of 'Atum'
(or the great creator sun God 'Ra'), personification of the "Breath
of Life" who held up the sky goddess 'Nut' from the earth god 'Geb'.
In form this would make 'Tefnut' a perfect female equivalent or
partner to the male Creator-God of the early Christians and Celts.
The moon symbol is undoubtably a later Celtic addition, possibly
added to indicate that this version of the middle eastern goddess
'Tefnut' is associated with the river 'Belisama' (Mersey) who's
original Egyptian/Phoenician name was 'Rhebelisama', goddess of
moon and heaven. While there is nothing to say a river can not be
represented by both the sun and moon, this might explain why cats
and cat goddesses of the moon are associated with the distinctly
'solar boat' shaped river Mersey. The Egyptians and Phoenicians
also tied their major solar and lunar dieties to rivers such as
the famous Ra and the River Nile association. While they are renowned
for trading tin from Cornwall, a Phoenician ship has been found
as far north as Scotland raising the possibility that the Phoenicians
first gave the name 'Rhebelisama' to the Mersey as long ago as 650
BC, well before the Romans used the name.
