On August 15, 1800, Mr. Ackermann issued at his Repository of Arts, 101 Strand, a series of six plates designed and etched in Rowlandson's boldest and most spirited style; and finished and coloured in almost exact imitation of the original drawings. Each plate contains three large distinct heads, festooned with attributes peculiar to the respective designs. It is not very clear whether these symbolical groupings, which are superior in execution to the average of Rowlandson's published works, were devised to be cut up for scrap-books, screens, or wall borderings; but they have become remarkably scarce since the date of publication, and sets of these typical heads (eighteen in all) are rarely met with at the present date. _Philosophorum._--The head of the philosopher closely resembles the conventional portrait accorded to Father Time, horn spectacles, forelock, grey beard and all. The globe, a sextant, mariner's compass, chart, telescope, dividers, bells, squares, thermometers, &c., make up the symbolical garland which depends from the ears of this emblem of knowledge. _Fancynina._--This figure is borne out by one of the artist's favourite types of female beauty, a well-featured, handsomely made and languishing-looking young lady, wearing a modish hat, all feathered, beaded, and flowered. The portrait of _Fancynina_ is festooned with such emblems of feminine frivolity as French rouge, Court sticking-plaister (for patches), ottar of roses, watches and trinkets, miniatures of admirers, an opera glass, a black domino or half-mask, a huge muff, parasol, fan, &c. _Epicurum._--An old gourmand in a red nightcap, whose flushed and blossoming countenance appears through a goodly string of sausages; a gridiron, a basting ladle, a cucumber, and other indications of creature comforts complete the emblems of this figure. _Penserosa._--The head of a tragic performer, modelled on that of one of the Gorgones is used to illustrate this figure. The Medusa head is entwined with serpents, and wreathed below with a festoon of bays, beneath which hang the dagger and bowl, and the manuscript of _Penserosa's_ tragic part. _Tally ho! rum!_--The head of a Nimrod, backed with a huntsman's cap, is the sign-piece of this figure; a _corne de chasse_ is hung round the sportsman's neck, and on it are spurs, horseshoes, whips, a gun, powder-flask, and game bag; a fox's head completes the group of emblems distinctive of _Tally ho! rum!_ _Allegoria._--The head of a rubicund, but young and well-featured, Bacchus does duty for _Allegoria_; heavy clusters of vine-leaves, and bunches of purple grapes and tendrils crown and surround the bucolic divinity; below is a Silenus mask; bacchanalian flutes, and pipes of Pan, complete the insignia.
