Thalia (Thaleia) the "Flourishing" is the muse of comedy and of playful and idyllic poetry, and is
       seen with a comic mask. She is sometimes seen with a crown of ivy and a crook. By Apollo,
       Thalia had the Corybantes, priests who castrated themselves in identification with the goddess,
       Cybele.

How light the strain when, decked in vernal bloom,            Thalia tuned her lyre of melody        from An Ode To Music, by James G. Percival
