O thou with dewy locks, who lookest down
Through the clear windows of the morning, turn
Thine angel eyes upon our western isle,
Which in full choir hails thy approach, O Spring!
The dew of an early spring or summer morning is joined with a woman’s hair. Her angel eyes, paints ‘her’ as some sort of higher being, and personifies spring as an angel or even a goddess. 
 The idea of morning and “dewy locks” is a common association from Renaisance and Petrarchan poetry. Blake takes the personification further, by describing the rest of Spring’s body: “eyes”, “feet”, etc. 
 In convention, personifications of Spring are usually female. However, Blake does not state whether his Spring is male or female. 
 
 The goddess imagery continues in the last part of the stanza when Blake writes that the western isle is in full choir as Spring approaches, like nature itself is ecstatic she had blessed them with her power.
