I quote from a magazine called The Parlor Portfolio or Post-Chaise Companion, published in London in 1724: To be seen, at Mr.John Syme's, Peruke maker, opposite the Mews, Charing Cross, the surprising and famous Italian Female Sampson, who has been seen in several courts of Europe with great applause.

She will absolutely walk, barefoot, on a red-hot bar of iron: a large block of marble of between two and three thousand weight she will permit to lie on her for some time, after which she will throw it off at about six feet distance, without using her hands, and exhibit several other curious performances, equally astonishing, which were never before seen in England.

She performs exactly at twelve o'clock, and four, and six in the afternoon.

Price half-a-crown, servants and children a shilling.
From the spelling, I judge that the person who selected this lady's title must have been more familiar with the City Directory than with the Scriptures.
In Edward J.Wood's Giants and Dwarfs, London, 1868, I find the following: A newspaper of December 19th, 1751, announces as follows: At the new theatre in the Haymarket, this day, will be performed a concert of musick, in two acts.

Boxes 3s., pit 2s., gallery 1s.
Between the acts of the concert will be given, gratis, several exercises of rope-dancing and tumbling.
