What is the author's style in Thyestes; Phaedra; the Trojan Women; Oedipus with Octavia by Seneca?

The five plays included in this collection were all originally written in Latin but have been translated into English and many other languages. The translation appears to be a semi-formal style of writing. The plays consist primarily of dialogue due to being written in the format of plays. The language spoken by different characters tends to distinguish the differences between classes. The language the royalty speaks differs drastically from the phonetically spelled language of the servants. More so than the actual language is the tone used to differentiate between the classes. Royalty is more likely to speak haughtily and with much demand whereas the lower class' tone is much more subservient and conciliating.
