P. only when the

Q. begin the evening

R. prayers at the temple

S. last lamp had been lit

T. did the priest

Explanation

1. 01

   "Only when" at the start turns the main clause round. P ends on "the", which needs a noun: S "last lamp had been lit".

2. 02

   Then "did" comes before the subject: T "did the priest", and a plain verb: Q "begin the evening", completed by R.

3. 03

   So the order is PSTQR: "Only when the last lamp had been lit did the priest begin the evening prayers at the temple."
