rival establishment. He exhibited several landscapes at the Royal Academy and the Suffolk Street Gallery between 1834 and 1861, besides many works at local exhibitions. He was very successful in his topographical views, a large collection of which is preserved at the Liverpool Free Library. His principal publication was entitled ‘Pictorial Relics of Ancient Liverpool, accompanied with Descriptions of Antique Buildings.’ 1843, fol.; 2nd ser. 1856. He also published: 1. ‘Views of Fleetwood-on-Wyre,’ Manchester, 1838, fol. 2. ‘Studies from the Folio of W. H.,’ Manchester, 1838, fol. 3. Three papers on linear perspective, in the ‘Art Journal.’ 1849–50. 4. ‘A Treatise on the Curvilinear Perspective of Nature, and its Applicability to Art,’ 1853, 8vo. 5. ‘Thoughts on Speculative Cosmology and the Principles of Art,’ 1870, 8vo. 6. ‘Hymns and Sacred Melodies,’ 4to. 7. ‘A Treatise on Skating.’ 8. Poems in manuscript and print (in the Liverpool Free Library). He died at Liverpool on 29 March 1882. One of his sons, William Herdman, published in 1864 a volume of ‘Views of Modern Liverpool.’

HERDSON, HENRY (fl. 1651), writer on mnemonics, probably received part of his education at Cambridge, as he terms that university his ‘dearest mother.’ He styled himself professor of the art of memory by public authority in the university of Cambridge. Afterwards he taught his art in London at the Green Dragon, against St. Antholin's Church. In or about 1649, when Dr. Thomas Fuller [q. v.] came out of the pulpit of St. Dunstan's-in-the-East, Herdson told him in the vestry, before credible people, that he, in Sidney College, Cambridge, had taught him the art of memory, but the doctor denied that he had seen Herdson before.
He wrote: 1. ‘Ars Mnemonica, sive Herdsonus Bruxiatus; vel Bruxus Herdsoniatus,’ London, 1651, 8vo. 2. ‘Ars Memoriæ: The Art of Memory made plaine,’ London, 1651, 8vo. These works are usually bound up together. The first is a republication of a portion of Brux's ‘Simonides Redivivus;’ the second, which is reprinted in Feinaigle's ‘Art of Memory’ (ed. 1813, pp. 297–317), consists of a meagre epitome of the principles of the mnemonic art.

HEREBERT or HERBERT, Saint (d. 687), hermit, resided on the island in Derwentwater which still bears his name. He was a disciple and close friend of St. Cuthbert, to whom he paid an annual visit for spiritual advice. The two friends both died on 20 March 687, Herebert suffering much from sickness before his death. In 1374 Thomas Appleby, bishop of Carlisle, directed the vicar of Crossthwaite to hold a yearly mass on St. Herebert's Isle on 15 April (the document is printed in Smith's edition of Bæda, App. p. 783). The remains of Herebert's cell are still shown. Mayhew, in his ‘Trophæa Congregationis Anglicanæ Ord. S. Benedicti,’ erroneously claims Herebert for his order.

HEREWALD (d. 1104), bishop of Llandaff, was a Welshman by birth, who had spent much of his time in England and was conspicuous for his piety. He was unanimously elected in 1056 bishop of Llandaff by Gruffydd ab Llewelyn, ‘the unconquered king of the Britons,’ Meurig ab Hywel, the king of Morganwg, and the magnates, secular and clerical, of Wales. He seems to have been consecrated by Joseph, bishop of St. David's. In the next century the chapter of St. David's pointed to this as an example of the exercise of archiepiscopal functions by the bishops of St. David's (Giraldus, De Invectionibus, in Opera, iii. 57, Rolls Ser.), but the act could have had no such significance at the time.
