Mynyddog Mwynfawr
Mynyddog Mwynfawr (variant orthographies include: Old Welsh Mynydawc Mwynvawr; Middle Welsh; Mynyddawg Mwynfawr) was, according to Welsh tradition founded on the early Welsh language poem Y Gododdin (attributed to Aneirin), a Brittonic ruler of the kingdom of Gododdin in the Hen Ogledd ("Old North"; a Welsh language term for Celtic Scotland and northern England). The traditional reading of Y Gododdin, accepted by most scholars, is that Mynyddog is king of Gododdin, perhaps with his court at Din Eidyn, modern Edinburgh.
