In consequence of this happy talent, when, according to the custom of the school, a Latin play was to be acted, a considerable part thereof was given to young Booth, who drew by the melody of his voice, and the gracefulness of his action, the applause of all the spectators, a circumstance which first fired him with theatrical ambition, much against the inclination of his father, who intended him for the church, and was therefore careful of his education.  This propension in our young Roscius, recommended him still more to the favour of Dr. Busby, who bestowed the most lavish encomiums upon him:  Busby was himself a great admirer of theatrical elocution, and admirably fitted by nature for the stage; when he was young, he obtained great applause in a part he performed in a play of Cartwright’s, and from that moment held theatrical accomplishments in the highest esteem.

When Booth had reached the age of eighteen, and the time approached when he was to have been sent to the university, he resolved to run any risk, rather than enter upon a course of life inconsistent with the liveliness of his temper, and the natural bent of his inclinations.  It happened that there was then in London one Mr. Ashbury, who had been long master of a company at Dublin, with whom young Booth became acquainted, and finding that under his direction there was no danger of his getting a livelihood, he quitted all other views, stole away from school, and went over to Ireland with Mr. Ashbury in 1698.[B]

He very soon distinguished himself on the stage at Dublin, where he had great natural advantages over most of his cotemporaries, especially in tragedy; he had a grave countenance, a good person, an air of dignity, a melodious voice, and a very manly action.  He spoke justly, his cadence was grateful to the ear, and his pronunciation was scholastically correct and proper.  He so far insinuated himself into the favour of English gentlemen in Ireland, and found his reputation growing to so great a heighth, that he returned home in 1701, to make a trial of his talents on the British stage.  He accordingly applied to lord Fitzharding, of the bedchamber to Prince George of Denmark, and was by him recommended to Mr. Betterton, who took him under his care, and gave him all the assistance in his power, of which Mr. Booth greatly profited.

Never were a tutor and pupil better met; the one was capable of giving the best instructions in his own performance, and the other had a promptness of conception, a violent propensity, and a great genius.  The first part Booth performed in London was Maximus in Valentinian, a play of Beaumont and Fletcher’s originally, but altered, and brought upon the stage by the earl of Rochester.  The reception he met with exceeded his warmest hopes, and the favour of the town had a happy effect upon him, in inspiring him with a proper degree of confidence without vanity.  The Ambitious Step-mother, a tragedy written by Mr. Rowe, in which that author has thrown out more fire, and heat of poetry, than in any other of his plays, was about this time introduced upon the stage; the part of Artaban was assigned to Booth, in which he raised his character to such a heighth, as to be reckoned only second to his great master.
