Y Prydydd Bychan
Y Prydydd Bychan was a medieval Welsh language court poet. His personal name is unknown. His father was the poet Phylip Brydydd. Prydydd was a grade of court poet, and bychan here has the meaning "junior" rather than the more usual "small" or "little", presumably to distinguish him from his father.
His surviving work is a small number of poems addressed to the princes of Deheubarth, in south Wales.
