Gwaith Dafydd Ap Gwilym NotesGDG 114; SPDG 23This poem sends the skylark as a love-messenger (llatai) to a married woman in Gwynedd. The two characteristics of the skylark which make it well-qualified to act as a messenger are its ability to fly high in the sky, avoiding the arrows of the jealous husband, and its habit of singing in flight. The central theme running through the description is the idea that the skylark's song as it flies heavenwards is in praise of God. 4. porthor Ebrill This suggests that the skylark's song was to be heard from April onwards (cf. 36.11-16). Today it is common throughout the year. 13. iawnGai angerdd According to the description of him in Culhwch ac Olwen Arthur's nephew Cai had the ability to make himself as tall as the highest tree whenever he wished (see CO 384-8). 38. capan This is understood in the sense of a cloak with a hood ('cape'), rather than the more common modern meaning 'cap' (see GPC 420 and cf. cwcyllwyd in 36.12). The reference is to the colour of the skylark's head and plumage which is darker than its breast.
