Spanish poet; lived at Amsterdam in the seventeenth century. He was one of the poets who celebrated the martyrdom of Abraham Nuñez Bernal in 1655; and his elegies form a part of the "Elogios" (Amsterdam, 1655). Daniel de Barrios ("Relacion de los Poetos," p. 56 = "R. E. J." 18:285) speaks of "an excellent Spanish poet, Custodio Lobo, otherwise called Moses Jeshurun Ribero" (died at Leghorn), some anti-Christian verses by whom he quotes. The similarity of their names induced Wolf ("Bibl. Hebr." , No. 1579d) to suppose the two poets to be identical.
