According to mainstream sources, the Muses – the Hellenic Goddesses of the Arts and Sciences – are either three, or nine, in total. However, in this book – The Greek Origin of Freemasonry, 1956, 2nd edition, p. 122 – there are ten of them:

Urania

Erato

Euterpe

Polymnia

Thalia

Terpsichore

Calliope

Cleo

Melpomene

Hestia

The first Muse – Urania – is the female version of the name of the planet Uranus. He is the God of the Sky: in Hellenic script this name means Sky (Ουρανóς). (Learn more here.) She is the Goddess of Astronomy: a Hellenic word meaning star (Astro) and law (Nomos). She rules Natural Law. (Learn more here.)

On pages 121 and 122 of the book that I have hyperlinked above, there is a poem that was sung to this Goddess in the Masonic Lodges of England during the eighteenth century:

“Wake the lute

and quiv’ring strings,

Mystic Truths

Urania brings;

Friendly visitant,

to thee the Depths

of Masonry;

Fairest of the

virgin choir,

warbling to the

golden Lyre;

welcome here,

The Art prevail

Hail, divine Urania,

Hail.”

Why are these Masonic English dudes singing this ode to a Hellenic Goddess?

The Muses – like other Hellenic Goddesses/Gods – represent forces, or aspects of Nature. It is interesting that in Hellenic lore, it is females that are associated with the sciences. 

As I have stated in previous articles, in the beginning, it was the women who were the custodians of the Masonic Mysteries, which in its purest form, was/is Universal Knowledge. This Gnosis was taught at Universities which originated in Hellas.
