Late Elizabethan drama contains a profusion of minced oaths, probably due to Puritan opposition to swearing. Seven new minced oaths are first recorded between 1598 and 1602, including ' for "By God's blood" from Shakespeare, " 'slight " for "God's light" from Ben Jonson, and " 'snails " for "God's nails" from the historian John Hayward. Swearing on stage was officially banned by the Act to Restraine Abuses of Players in 1606, and a general ban on swearing followed in 1623. Other examples from the 1650s included " 'slid" for "By God's eyelid" (1598), ' for "By God's foot" (1602), and ' for "By God's hooks" (referring to the nails on Christ's cross). In the late 17th century, ' meant "oh God", and "" for "By God's bodkins nails" in 1709.
