Count Lumiares, in his work on pottery of Saguntum ("Barros Saguntinos," Valencia, 1779, 8vo), mentions having examined more than 1500 specimens of pottery of different kinds, which he classifies in four groups: grey pottery, cream-coloured pottery, yellow pottery and red glazed ware, with ornamentation in relief (Samian ware); this ornamentation constitutes, in my opinion, the only distinctive feature of the pottery made at Saguntum. Remains of this pottery are very frequently found in the ruins of former Roman cities; a much larger number of specimens of all kinds have appeared since Count Lumiares wrote his book, none however differ materially from the terra-cottas of the Roman period found in Italy, or in other countries. Some of the marks are identical with those given by Birch and several authors who have written on Roman pottery; hence it would appear that this industry was imported into Spain, or the forms and marks copied there to a very large extent. [Illustration: SAMIAN BOWL.] The number of inscriptions and potters' marks met with on the vases and fragments found in Spain is very great. Students who take a special interest in this subject will find full details in Dr. Emile Hübner's important work, "Inscrip. Hispaniæ Latinæ," Berlin, 1869. This writer has collected the greatest number of inscriptions. He mentions 43 which appear on bricks, 36 on vases and drinking vessels, 63 on lamps, 579 on vases of red pottery, 115 inscriptions of doubtful reading, 21 which are incomplete, and 56 written by hand. He gives us, besides, other marks without inscriptions, representing hands, horses, rabbits, butterflies, bees, flowers, etc. In an inedited history of the ancient city of Emporion (Cataluña) [MS., Acad. of Hist., Madrid], the author, Dr. Joaquin Botet y Sisó, has collected 198 potters' marks. A large number are still unpublished which have been met with on fragments of pottery found in Extremadura and Andalucia; we may therefore confidently assert that the number amounts to upwards of 1500. During the Visigothic monarchy, after the downfall of the Roman empire, which lasted until the invasion of the Arabs in the 8th century, the same style of ceramic industry, copied from the Romans, continued in Spain. No special study has been made of the pottery of this epoch, but, judging by the large amount of fragments of vessels for domestic use, which are constantly found in ruins of the Visigothic period, there can be no doubt that pottery continued to be manufactured in Spain. What San Isidoro, who died in 636, says in his "Etimologies, Book xx.," confirms this opinion, and undoubtedly refers to vessels similar to those of the Roman period. (_De vasis Escariis, potoriis vinariis et aquariis, oleariis, coquinariis et luminariorum._) After the Roman domination and Visigothic monarchy, ceramic art in Spain may be divided into the following groups:--
