It was the original design of the author of this Dictionary to give a minute explanation of all the names of which Pliny and other ancient geographers make mention; but, upon a second consideration of the subject, he was convinced that it would have increased his volume in bulk, and not in value. The learned reader will be sensible of the propriety of this remark, when he recollects that the names of many places mentioned by Pliny and Pausanias occur nowhere else in ancient authors; and that to find the true situation of an insignificant village mentioned by Strabo, no other writer but Strabo is to be consulted. This Dictionary being undertaken more particularly for the use of schools, it has been thought proper to mark the quantity of the penultimate of every word, and to assist the student who can receive no fixed and positive rules for pronunciation. In this the authority of Smethius has been followed, as also Leede’s edition of Labbe’s Catholici Indices. As every publication should be calculated to facilitate literature, and to be serviceable to the advancement of the sciences, the author of this Dictionary did not presume to intrude himself upon the public, before he was sensible that his humble labours would be of some service to the lovers of the ancient languages. The undertaking was for the use of schools, therefore he thought none so capable of judging of its merit, and of ascertaining its utility, as those who preside over the education of youth. With this view, he took the liberty to communicate his intentions to several gentlemen in that line, not less distinguished for purity of criticism, than for their classical abilities, and from them he received all the encouragement which the desire of contributing to the advancement of learning can expect. To them, therefore, for their approbation and friendly communications, he publicly returns his thanks, and hopes that, now his labours are completed, his Dictionary may claim from them that patronage and that support to which, in their opinion, the specimen of the work seemed to be entitled. He has paid due attention to their remarks, he has received with gratitude their judicious observations, and cannot pass over in silence their obliging recommendations, and particularly the friendly advice he has received from the Rev. R. Valpy, master of Reading School. For the account of the Roman laws, and for the festivals celebrated by the ancient inhabitants of Greece and Italy, he is particularly indebted to the useful collections of Archbishop Potter, of Godwyn, and Kennet. In the tables of ancient coins, weights and measures, which he has annexed to the body of the Dictionary, he has followed the learned calculations of Dr. Arbuthnot. The quoted authorities have been carefully examined, and frequently revised: and, it is hoped, the opinions of mythologists will appear without confusion, and be found divested of all obscurity.
