 The influence of "Phaedra" in particular can further be seen in dramas of 16th and 17th century France with Robert Garnier's "Hippolyte" (1573) and Racine's "Phèdre" (1677).According to historian Helen Slaney, Senecan tragedy "virtually disappeared" in the 18th century as drama became more regulated and "sensibility supplanted horror".Seneca's "Phaedra" saw a resurgence of influence in the 20th century with productions of Tony Harrison's "Phaedra Britannica" (1975), Sarah Kane's "Phaedra's Love" (1996).
