In the words of his poetic biographer, Blind Harry the minstrel:
Wallace about him, from his childhood, kept,
Where'er he went, whether he walked or slept,
A psalter book, where he beseech'd a knight,
Lord Clifford, might be brought unto his sight.
Which done, he caus'd a priest upon the place,
To hold it open straight before his face,
On which he look'd, sometimes his eyes up cast,
Religiously unto his very last.
