This is a gilt-pewter medal made by Thomas Simon in the 17th century in England. The obverse of this medal represents the profile bust of Oliver Cromwell and the reverse shows the Long Parliament in session.
Oliver Cromwell (1599-1658), was both revered and loathed in Victorian times. Numerous admirers commissioned portraits, including busts. The great Puritan general of the Parliamentary Army during the English Civil War, Oliver Cromwell (1599-1658) lived with his family as a gentleman farmer until 1640, when he was elected MP for Cambridge in the Short and Long Parliaments. A fiercely religious idealist who spoke out against oppression, Cromwell and his troops successfully defeated the Royalists in a string of military victories before he emerged as the creator of the New Model Army in 1645. The aftermath of the execution of King Charles I in January 1649 saw Cromwell lead successful campaigns to conquer Ireland and Scotland, as well as managing the crushing defeat of Prince Charles's attempt to recover the Crown at Worcester in 1651, and the launching of victorious wars against the Dutch, Spain, and Tunisian piracy. In 1653 England was established as a Commonwealth with Cromwell designated Lord Protector, a title he retained until his death in 1658.

Thomas Simon (b London, 1618; d London, 1665), and his brother Abraham (b. London, 1617; d ?1692) are among the finest British medallists. They worked together. Abraham made the wax models and Thomas usually chased and then signed the finished work.

Abraham worked for Queen Christina of Sweden and in Holland before returning to England in ca. 1643.
In 1645 he was appointed jointly with his brother Engraver of Coins and Seals at the Royal Mint. From around this time they produced many cast and chased portrait medals of distinguished contemporaries.
