Thanks for the reply. Yes we use "Mean Fomhair" for September, lit."middle of Autumn", just as "Deireadh Fomhair" for October "End of Autumn"; before Mí na Samhna ("Month of Samhain", November) comes in. I was always curious about this, that archaeology is clear about alignments to the solstices and indeed the alignment of the mid-winter sun at the December solstice was retained in oral folklore in the area of Meath as far as I know, yet no mention of a "seasonal name" for this calendar point and no surviving calendar custom (other than recognition of the solstice sun in December at Newgrange) is evident (to me so far) which would imply indeed that it wasn't celebrated or recognised as an important marker of the year as it was in stone age times. I was just curious if anything had turned up in any mediaeval texts you studied. There is a tract on cosmology in the library of the RIA in Ireland but I think it's a translation into Irish of a foreign treatise on same and I cannot remember the period. (Astrocelt and I referenced it some time back in our discussions, so I must check into again).
