Polly Morgan's latest show at Haunch of Venison represents a new conceptual watershed for the artist who has often been called the "queen of taxidermy." Exploring ideas about the journey of the soul after the point of death, Psychopomps presents us with the various winged vessels that Morgan has created to carry the spirit across the endless void. Here, she talks to John-Paul Pryor about employing her unique talents to evoke a sense of childlike wonder.
