St. Lawrence Church is situate on the north side of Cateaton Street, "and is denominated," says Maitland, "from its dedication to Lawrence, a Spanish saint, born at Huesca, in the kingdom of Arragon; who, after having undergone the most grievous tortures, in the persecution under Valerian, the emperor, was cruelly broiled alive upon a gridiron, with a slow fire, till he died, for his strict adherence to Christianity; and the additional epithet of Jewry, from its situation among the Jews, was conferred upon it, to distinguish it from the church of St. Lawrence Pulteney, now demolished.

"This church, which was anciently a rectory, being given by Hugo de Wickenbroke to Baliol College in Oxford, anno 1294, the rectory ceased; wherefore Richard, Bishop of London, converted the same into a vicarage; the advowson whereof still continues in the same college. This church sharing the common fate in 1666, it has since been beautifully rebuilt, and the parish of St. Mary Magdalen, Milk Street, thereunto annexed." The famous Sir Richard Gresham lies buried here, with the following inscription on his tomb:—

"Here lyeth the great Sir Richard Gresham, Knight, some time Lord Maior of London; and Audrey, his first wife, by whom he had issue, Sir John Gresham and Sir Thomas Gresham, Knights, William and Margaret; which Sir Richard deceased the 20th day of February, An. Domini 1548, and the third yeere of King Edward the Sixth his Reigne, and Audrey deceased the 28th day of December, An. Dom. 1522."

There is also this epitaph:—

"Lo here the Lady Margaret North,
In tombe and earth do lye;
Of husbands four the faithfull spouse,
Whose fame shall never dye.
One Andrew Franncis was the first,
The second Robert hight,
Surnamed Chartsey, Alderman;
Sir David Brooke, a knight,
Was third. But he that passed all,
And was in number fourth,
And for his virtue made a Lord,
Was called Sir Edward North.
These altogether do I wish
A joyful rising day;
That of the Lord and of his Christ,
All honour they may say.
Obiit 2 die Junii, An. Dom. 1575."

In Ironmonger Lane, inhabited by ironmongers temp. Edward I., is Mercers' Hall, an interesting building.

The Mercers, though not formally incorporated till the 17th of Richard II. (1393), are traced back by Herbert as early as 1172. Soon afterwards they are mentioned as patrons of one of the great London charities. In 1214, Robert Spencer, a mercer, was mayor. In 1296 the mercers joined the company of merchant adventurers in establishing in Edward I.'s reign, a woollen manufacture in England, with a branch at Antwerp. In Edward II.'s reign they are mentioned as "the Fraternity of Mercers," and in 1406 (Henry IV.) they are styled in a charter, "Brothers of St. Thomas à Becket."

Mercers were at first general dealers in all small wares, including wigs, haberdashery, and even spices and drugs. They attended fairs and markets, and even sat on the ground to sell their wares—in fact, were little more than high-class pedlers. The poet Gower talks of "the depression of such mercerie." In late times the silk trade formed the main feature of their business; the greater use of silk beginning about 1573.

The mercers' first station, in Henry II.'s reign, was in that part of Cheap on the north side where Mercers' Hall now stands, but they removed soon afterwards higher up on the south side. The part of Cheapside between Bow Church and Friday Street became known as the Mercery. Here, in front of a large meadow called the "Crownsild," they held their little stalls or standings from Soper's Lane and the Standard. There were no houses as yet in this part of Cheapside. In 1329 William Elsing, a mercer, founded an hospital within Cripplegate, for 100 poor blind men, and became prior of his own institution.

In 1351 (Edward III.), the Mercers grew jealous of the Lombard merchants, and on Midsummer Day three mercers were sent to the Tower for attacking two Lombards in the Old Jewry. The mercers in this reign sold woollen clothes, but not silks. In 1371, John Barnes, mercer, mayor, gave a chest with three locks, with 1,000 marks therein, to be lent to younger mercers, upon sufficient pawn and for the use thereof. The grateful recipients were merely to say "De Profundis," a Pater Noster, and no more. This bequest seems to have started among the Mercers the kindly practice of assisting the young and struggling members of this Company.
