I Was Crom Dubh Once

I was Crom Dubh once,
Buried in the mound,
I was the Dagda once,
My club across the land,
I was Bran the Blessed once,
My head beneath the hill,
I was Kronos once,
My stone sickle in the sky,
I was Osiris once,
My body across the land,
I was Odin once,
Ygg was I once,
Ere that I was Thund,
Who am I?
