University researchers have been awarded a grant of almost £900,000 to produce a new edition of the works of a medieval "giant" of Welsh poetry.
Guto'r Glyn fought on the Yorkist side in the War of the Roses
The grant, to the University of Wales' Centre for Advanced Welsh and Celtic Studies, is for research on the works of 15th Century poet Guto'r Glyn.
The award is thought to be the largest of its kind to a Welsh university.
Glyn also fought in the Hundred Years War. The five-year research on him will include a Welsh medieval life website.
Guto'r Glyn (c1435-c1493) wrote poems of praise to nobles and fought on the Yorkist side in the War of the Roses.
He was believed to be from Denbighshire and wrote during a period in Welsh literature known as the "great century" because of the amount of poetry produced.
As a soldier, he fought in France during the Hundred Years War, supported the Yorkist cause in the War of the Roses, and received patronage from noble families throughout Wales.
Glyn's Welsh-language poetry provides insights into the lives of the nobility including descriptions of feasts, fine wines, costumes, military battles, domestic relations and animals.
The £879,383 grant, from the Arts and Humanities Research Council (AHRC), will allow a team of researchers at the centre to prepare a new bilingual edition - on the internet and in print - of his poetry.
The AHRC funds research and postgraduate study in the UK's higher education institutions.
Geraint H Jenkins, director of the Centre for Advanced Welsh and Celtic Studies, based in Aberystwyth, said the grant was "extremely large grant in UK terms so is very significant in Welsh terms".
Prof Jenkins added that the programme of research and publication would help increase knowledge of Guto'r Glyn and his poetry.
He said: "There's a very old edition of his work which is incomplete.
"But he is among the giants of Welsh poetry and this new edition will bring him into the light.
"Guto'r Glyn is an important historical figure - he fought in the Hundred Years War and was at Bosworth Field [where Richard III was defeated by Henry Tudor].
"He is a witness to lots of things that were happening in 15th Century Britain."
The project, which includes production of a new collection of Guto'r Glyn's poetry, a bilingual website featuring images of the original manuscripts and a second website concentrating on Welsh life during the poet's lifetime, will be led by Ann Parry Owen.
Dr Parry Owen, who specialises in medieval Welsh poetry, said a new edition of Guto'r Glyn's work was long overdue.
She said: "I was delighted to receive this award because it enables the centre to bring together leading scholars to edit the work of one of the finest poets in late medieval Britain."
The project is due to begin in January 2008 and is expected to be completed five years later.
The seven members of the research team will be based in Aberystwyth, Swansea and Cardiff.
The £879,383 grant is believed to be the largest grant ever made by the Arts and Humanities Research Council to a higher education institution in Wales.
