Snell was born in 1670, died in 1733. This book of his was published in 1712, having been engraved by George Bickham. Bickham commented on Snell's work in the introduction:
"the Originals of that BOOK were the Best I ever wrought after: And tho' I have for the most part, kept close to the Proportion of the Letter, yet I think it impossible for any Engraver to Reach that Delicacy and Spirit, that is produced from the Freedom and Boldness of his Hand"
Snell was apprenticed as a boy to a writing master of no particular note, but through his tireless study and practise from engraved works of Louis Barbedor (the French writing master) he attained great skill.
Joseph Champion was a pupil of Snell.
Snell's work was greatly admired at the time.
Snell was also an expert accountant, bookkeeper and arithmetician and taught those subjects as well as penmanship.
