Just a thought game: Trinus Samoni is the 17th day of the first month of the year.

Some of the months in our calendar are named for there position within the original calendar (Roman):

December is the 10th month of the year

November is the 9th month of the year

October is the 8th month of the year
September is the 7th month of the year
August (formerly in Latin: Sextilis) is the 6th month of the year
July would be the 5th month of the year
June would be the 4th month of the year
May would be the 3rd month of the year
April would be the 2nd month of the year
March would be the 1st month of the year

The first month of the Roman calendar was March. Coincidental the Irish for the past thousand years, on the 17th day of the first month in the Roman calendar, have been breaking lent (eating meat and drink) in the name of their most favorite saint. That is saint that Mackenzie thought had replaced Lugh in tales regarding to battle to free the summer maiden from the grasp of winter Cailleach. (If I was to think of a Celtic god associated with the distributed number three, I would have to go Lug as present in his threefold form.)

So is it coincidental that Trinus Samoni falls on same day of year as St Patrick's Day ? (Seventeen day of the first month of the year.)

In 1897 the Coligny calendar was found. The 17th day of month of Samon has the following enteries:

Year 3 - missing

If I accept that PRINI and PRINO are scribal errors for TRINI and TRINO. Then Romano-Gaulish TRINVX (TRINUS)/TRINO/TRINI has a strong resemblance to the Latin TRINUS/TRINO/TRINI the cognate of Old Irish Trian (plural form: Traene).

Then Romano-Gaulish TRINVXSAMO is a cognate of the Old Irish Traene Samna ?

Question: am I right to consider Old Trian as a cognate of Latin Trinus? And sharing the same root *tri-(s)no-with it and the Old English þrinen (Middle English threnen) from Old Icelandic þrennr?

Given that Latin Trinus is a  form of the distributive numeral three, and that Trianach from Trian was also considered to be the distributive numeral three:

Edward Lhuyd, Archaeologia Britannica, Volume 1 (Oxford 1707)
"TRIANACH, Three by three. Pl."
John O'Brien and Edward Lhuyd, Focalóir Gaoidhilge-sax-bhéarla (Paris 1768):
"TRIANACH, three by three, terni."
William Shaw, A Galic And English Dictionary (London 1780):
"TRIANACH, Three by three, of the third part"
Edward O'Reilly, An Irish-English Dictionary with a Compendious Irish Grammar (Dublin 1821):
"TRIANACH, three by three, of the third part, thirdly"
Robert Archibald Armstrong, A Gaelic Dictionary in Two Parts (London 1825):
"TRIANACH, a. (from trian.) Three by three; of the third part."
Dictionarium Scoto-Celticum (Edinburgh 1828):
"TRIANACH, (Trian), Of the third part: trinus, ternus. "Trianach Iàn." C. S. One third full : plenus usque ad tertiam partem."
Norman Macleod, Daniel Dewar, A Dictionary of the Gaelic Language in Two Parts (Glasgow 1831):
"TRIANACH, adj. (Train,) Of the third"
Edil (online at accessed 07 24 2007:
"tríanach o, a (1 trían ) threefold, tripartite"
"treinech o, a (trí) In Mod. Ir. trénach. threefold, tripartite"

Then Old Irish Trian is equivalent to the Latin Trinus?
