The name "Gaster I" was introduced by Mendel Metzger in his article entitled "The Earliest Engraved Italian Megilloth" (see "Bibliography"). The type was named after Moses Gaster (1856–1939), the rabbi, scholar, and manuscript collector, who owned a scroll adorned with this pattern (at present this is the scroll Gaster Hebrew MS 710 stored in the John Rylands Library in Manchester). At least 25 manuscripts representing this type are still extant and are preserved in private and institutional collections. For their descriptions see "Related objects".
The pattern features a number of decorative elements common with the scrolls of Klagsbald type.
