The text of this play lends very little to the race or ethnicity of the characters except for one named Mustafa who is an Albanian. Beyond that, there is no reference besides being Venetian and European. However, gender seems to matter significantly. If Anna Galactia were played by a man it would completely alter major themes of the play. It would also alter relationships that Galactia is suppose to have with Carpeta and her daughters and mainly everyone else's view of her being a female painter. I happen to believe that altering any of the major character's gender would result in completely changing author's intention and even further than that it would create a sense of confusion amongst the audience. I strongly believe that gender should stay as intended except for maybe more minor roles such as the Sketchbook or Sailor.
