Whereat Cadwallin wroth, shall forth issew,
2 And an huge hoste into Northumber lead,
With which he godly Oswald shall subdew,
4 And crowne with martyrdome his sacred head.
Whose brother Oswin, daunted with like dread,
6 With price of siluer shall his kingdome buy,
And Penda, seeking him adowne to tread,
8 Shall tread adowne, and do him fowly dye,
But shall with gifts his Lord Cadwallin pacify.
