The writers of the period abound in notices of the unparalleled growth of trade and commerce. Harrison laments "that every function and several vocation striveth with other, which of them should have all the water of commodity ran into her own cistern[125]." Ample openings for capital broke through the old prejudices against the taking of interest. "Usury" as it was called--"a trade brought in by the Jews--is now perfectly practiced almost by every Christian, and so commonly that he is accompted but for a fool that doth lend his money for nothing[126]." The English workman too was growing rich and lazy in the sunlight of prosperous times, so that "strangers" were frequently preferred to native craftsmen as "more reasonable in their takings, and less wasters of time by a great deal than our own[127]." This was the commencement of the period of Shrewsbury's greatest prosperity. Edward IV.'s erection of the Court of the President and Marches of Wales (1478) was a material cause of the advent of peace to the Borders. Henry VII. could gratify national sentiment by tracing his descent from Owen Tudor: he gave it a practical turn by placing his son Arthur at Ludlow as ruler of the principality. The Welshmen had thus begun to feel that their union with England was a real one before Henry VIII. finally incorporated the country with the English kingdom. [Sidenote: _Increase of comfort._] The cessation of Welsh distractions had greatly favoured the advancement of Shrewsbury. Its grammar school--founded by Edward VI.--as the entrance register of Thomas Ashton, its first Headmaster, evidences, attracted scholars from a very wide area, and helped to bring renown and wealth to the town. Shrewsbury too was the market to which the Welsh cloth trade naturally gravitated, though the town had powerful rivals with which to contend. In the reign of Elizabeth it employed six hundred shearmen in the woollen industry. Camden, writing in 1586, describes it as "a fine city, well-inhabited and of good commerce, and by the industry of the Citizens is very rich." From this period date the substantial homes of the tradesmen of Tudor times which still survive in not inconsiderable numbers to give so much picturesqueness to the streets of the town. This was the era of improvements in domestic architecture. "If ever curious building did flourish in England," says Harrison[128], "it is in these our years." Ireland's mansion, which dates from 1570, and the house at the south-east corner of the Market Square, built by John Lloyd in 1579, are existing examples of this "curious building." Their elegance, no less than their stability, betokens the advancement of manners as well as of wealth. Though these houses are "yet for the most part of strong timber" "brick or hard stone[129]" were beginning to be largely used. Rowley's mansion (1618) is said to have been the first house in the town built wholly of these materials.
