context: The first attribution to Shakespeare of this play, originally drafted in 1605 or 1606 at the latest with its first known performance on St. Stephen's Day in 1606, was a 1608 publication in a quarto of uncertain provenance, in which the play is listed as a history; it may be an early draft or simply reflect the first performance text. The Tragedy of King Lear, a more theatrical revision, was included in the 1623 First Folio. Modern editors usually conflate the two, though some insist that each version has its own individual integrity that should be preserved.
