The sea is the home of piety. Coast towns, ports, and havens, reached after voyages of peril, are invariably notable for their places of worship, and for customs which speak touchingly--like the blessing of fishermen's nets, for instance--of lives spent in uncertainty and danger. Thus, the leading characteristic of Elizabethan London being its association with the sea and its dependence on the river, we find that its next most striking characteristic was the extraordinary number of churches it contained. The great cathedral predominated more pronouncedly than its modern successor. From the hill on which it was based it reared its vast bulk; its great spire ascended the heavens, and the multitude of church towers and spires and belfries throughout the city seemed to follow it. The houses were small, the streets were narrow; but to envisage the city from the river, or from the Surrey side, was to have the eye led upwards from point to point to the summit of St. Paul's. The dignity and piety of London were thus expressed, in contradiction to human foibles and failings so conspicuous in Elizabethan drama. The spire of St. Paul's was destroyed by lightning early in the reign of Elizabeth; and the historian may see much significance in the fact that it was not rebuilt, even in thanksgiving and praise for the deliverance from the Great Armada. The piety of London dwindled until it flamed forth anew in the time of the Puritan revolt. The bridge was carried on nineteen arches. It had a defensive gate at the Southwark end, and another gateway at the northern end. In the centre was a beautiful chapel, dedicated to Thomas à Becket, and known as St. Thomas of the Bridge. Houses were built on the bridge, mostly shops with overhanging signs, as in the streets of the city. Booksellers and haberdashers predominated, but other trades were carried on also. After the chapel, the most conspicuous feature of the bridge was "Nonesuch House," so called to express the wonder that it was constructed in Holland entirely of wood, brought over the water piece by piece, and put together on the bridge by dovetailing and pegs, without the use of a single metal nail. Adjoining the northern gateway was an engine for raising water by means of a great wheel operated by the tide. Near the Southwark end were corn-mills, worked on the same principle, below the last two arches of the bridge. The gateway at the Southwark end, so well shown in Visscher's view of London, was finished in 1579, and the traitors' heads, which formerly surmounted a tower by the drawbridge, were transferred to it. Travellers from the south received this grim salutation as they approached the bridge, which led into the city; and when they glanced across the river, the Tower frowned upon them, and the Traitors' Gateway, like teeth in an open mouth, deepened the effect of warning and menace.
