England became the first team to score 500 runs on the opening day of a Test match Thursday, putting Pakistan to the sword in Rawalpindi.
Four English batsmen scored centuries as the tourists cantered to 506-4 at the close of play.
The previous record for runs on the first day was the 494 Australia accumulated against South Africa in Sydney in 1910.
More than 500 runs in a day has only been achieved on four other occasions — three times by England and once by Sri Lanka — but never on the opening day of a Test.
The record is the 588 England ran up on day two of a test against India in 1936.
