In 1633, plans were made for a new one-off tax on house-rent, or "mail", intended to pay the stipends of Edinburgh's clergy. At the request of Charles I, full power and commission was given "for passing through the whole city andtrying of what mail every tenement, dwelling house, low tavern, cellar or chamber", and an inventory was taken, which survives in manuscript form in the Edinburgh City Archives. While it would seem that the tax was never actuallycollected and so was a failure in terms of municipal fund-raising, it left an incredibly detailed record of the socio-economic and political structures of the Scottish capital. Giving information on landlords, tenants, rental andannuity for over 900 businesses and 3,900 houses, the record enables the topographies of Edinburgh down to house-by-house level to be reconstructed; whilst Cardinal Beaton's Lodgings, or the Pudding Market, no longer survive, theinventory sheds important light on these missing structures and allows for a fuller interpretation of the still extant buildings, such as Mary King's Close, or Gladstone's Land. Now published in its entirety for the first time, this valuable record gives us an exceptional view of an early modern capital and an unprecedented insight into the socio-economic composition and landscape of early modern Edinburgh, forming an invaluable resource for those interested in topics such as the demographic and economic history of preindustrial towns, urban topography and the local and genealogical history of Scotland's capital. It is particularly useful in illuminating those sections of society so often hidden from history, and giving a rare window into the people and property of Edinburgh on the eve of revolution. The volume also includes an extensive historical introduction explaining the nature, context and utility of the records.
