The Jewish Encyclopedia refers to a Mordecai ben Ruben Ibn Attar who arranged the printing of 'Azharot' (Exhortations) by Solomon Ibn Gabirol and Isaac ben Reuben [Albargeloni], published by Solomon Proops in Amsterdam in 1721. I cannot seem to find it anywhere online. Any ideas where I might find it? In 2017 Ton posted a list of despachos from Amsterdam to North Africa. (Available here: https://www.facebook.com/groups/TheSepardicDiaspora/permalink/1958109654448666/) On the list there was a Mordechay Abenatar who appeared twice. He was sent from Amsterdam to Morocco in 1717 with a subsidy of 100 guilders, and again in 1725 with 50 guilders. He was likely the same as the Mordecai as above. Thanks!
