And according to the surmisers, that is what he did. Yes, although there was no one in Stratford able to teach him these things, and no library in the little village to dig them out of. His father could not read, and even the surmisers surmise that he did not keep a library.
It is surmised by the biographers that the young Shakespeare got his vast knowledge of the law and his familiar and accurate acquaintance with the manners and customs and shop-talk of lawyers through being for a time the CLERK OF A STRATFORD COURT; just as a bright lad like me, reared in a village on the banks of the Mississippi, might become perfect in knowledge of the Behring Strait whale-fishery and the shop-talk of the veteran exercisers of that adventure-bristling trade through catching catfish with a "trot-line" Sundays. But the surmise is damaged by the fact that there is no evidence--and not even tradition--that the young Shakespeare was ever clerk of a law court.
It is further surmised that the young Shakespeare accumulated his law-treasures in the first years of his sojourn in London, through "amusing himself" by learning book-law in his garret and by picking up lawyer-talk and the rest of it through loitering about the law- courts and listening. But it is only surmise; there is no EVIDENCE that he ever did either of those things. They are merely a couple of chunks of plaster of paris.
There is a legend that he got his bread and butter by holding horses in front of the London theatres, mornings and afternoons. Maybe he did. If he did, it seriously shortened his law-study hours and his recreation-time in the courts. In those very days he was writing great plays, and needed all the time he could get. The horse-holding legend ought to be strangled; it too formidably increases the historian's difficulty in accounting for the young Shakespeare's erudition--an erudition which he was acquiring, hunk by hunk and chunk by chunk every day in those strenuous times, and emptying each day's catch into next day's imperishable drama.
He had to acquire a knowledge of war at the same time; and a knowledge of soldier-people and sailor-people and their ways and talk; also a knowledge of some foreign lands and their languages: for he was daily emptying fluent streams of these various knowledges, too, into his dramas. How did he acquire these rich assets?
In the usual way: by surmise. It is SURMISED that he travelled in Italy and Germany and around, and qualified himself to put their scenic and social aspects upon paper; that he perfected himself in French, Italian and Spanish on the road; that he went in Leicester's expedition to the Low Countries, as soldier or sutler or something, for several months or years--or whatever length of time a surmiser needs in his business--and thus became familiar with soldiership and soldier-ways and soldier-talk, and generalship and general-ways and general-talk, and seamanship and sailor-ways and sailor-talk.
Maybe he did all these things, but I would like to know who held the horses in the meantime; and who studied the books in the garret; and who frollicked in the law-courts for recreation. Also, who did the call-boying and the play-acting.
For he became a call-boy; and as early as '93 he became a "vagabond"--the law's ungentle term for an unlisted actor; and in '94 a "regular" and properly and officially listed member of that (in those days) lightly-valued and not much respected profession.
Right soon thereafter he became a stockholder in two theatres, and manager of them. Thenceforward he was a busy and flourishing business man, and was raking in money with both hands for twenty years. Then in a noble frenzy of poetic inspiration he wrote his one poem--his only poem, his darling--and laid him down and died:
Good friend for Iesus sake forbeare To digg the dust encloased heare: Blest be ye man yt spares thes stones And curst be he yt moves my bones.
He was probably dead when he wrote it. Still, this is only conjecture. We have only circumstantial evidence.
