Unto the toure of famous doctrine:
Who that wil learne must be ruled by reason
And with all his diligence he must enclyne
Slouthe to eschue and for to determine,
And set his hert to be intelligible;
To a willyng harte is nought impossible.
Besyde the ymage I adowne me sette,
After my laboure my selfe to repose,
Tyll at the last with a gaspyng nette
Slouth my head caught with his whole purpose.
