Henry Lawes. Henry Lawes served as music tutor to the Bridgewater family. He was a noted composer and member of the King's Music. He appeared in the first production of A Mask as the Attendant Spirit, or Thyrsis. Apparently he was also responsible for the 1637 publication of A Mask; see his prefatory letter. See the 1645 title page from Early English Books Online.

Eclog. 7. Virgil's Eclogues 7.27-28 where Thyrsis says "Shepherds of Arcady, crown with ivy your rising bard, that Codrus’ sides may burst with envy; or, should he praise me unduly, wreathe my brow with foxglove, lest his evil tongue harm the bard that is to be." Or "predestined bard." Milton appears to use this epigraph as an antidote to the more Cavalier tone of Moseley's front matter.
