We have a faithful representation of London, as it appeared at the end of the Commonwealth period, in Newcourt and Faithorne's valuable Plan of London, dated 1658. A long growth of houses north of the Thames is seen stretching from the Tower to the neighbourhood of Westminster Abbey. Islington is found at the extreme north of the plan unconnected with the streets of the town, Hoxton connected with the city by Shoreditch, Bethnal Green almost alone, and Stepney at the extreme north-east. South of the Thames there are a few streets close to the river, and a small out-growth from London Bridge along the great southern road containing Southwark and Bermondsey. There is little at Lambeth but the Archbishop's Palace and the great marsh. On this plan we see what was the condition of the Haymarket and Piccadilly before the Restoration. This was soon to be changed, for between the years 1664 and 1668 were erected three great mansions in the "Road to Reading" (now Piccadilly), viz., Clarendon House (where Bond and Albemarle Streets now stand), Berkeley House (on the site now occupied by Devonshire House), and Burlington House. Piccadilly was the original name of the district after which Piccadilly Hall was called. The latter place was situated at the north-east corner of the Haymarket, nearly opposite to Panton Square, and close by Panton Street, named after Colonel Thomas Panton, the notorious gamester, who purchased Piccadilly Hall from Mrs. Baker, the widow of the original owner. There is much to be said in favour of associating the name of some well-known man with the London of his time, and thus showing how his descriptions illustrate the chief historical events of his time, with many of which he may have been connected. In the case of Samuel Pepys, we can see with his eyes many of the incidents of the early years of the Restoration period, and thus gain an insight into the inner life of the times. Pepys lived through some of the greatest changes that have passed over London, and in alluding to some of these we may quote his remarks with advantage. His friend, John Evelyn, also refers to many of the same events, and may also be quoted, more particularly as he was specially engaged at different periods of his life in improving several parts of London. We are truly fortunate in having two such admirable diarists at hand to help us to a proper understanding of the course of events and of the changes that took place in London during their long lives.
