At roughly four thousand lines, the second quarto version of Hamlet -- the closest surviving version to what Shakespeare first wrote in late 1599 could not have been performed uncut. Though the Elizabethan stage dispensed with time-consuming intermissions and scenery changes, this version would still have taken four hours to perform; even at top speed, actors couldn't rattle off much more than a thousand lines of verse an hour. With outdoor performances beginning at two in the afternoon and the sun setting at around five o'clock, an uncut Hamlet staged in late fall or winter would have left actors stumbling about on a dark stage. Contemporary references to other plays mention their running time as being closer to two hours.
